Firefox Community Forum

Several weeks ago, I was attempting to upgrade from Windows 10 to Windows 11. In the process, I deleted Firefox (using Revo Uninstaller) and then reinstalled it, downloading it from the Mozilla website. Unfortunately, it didn’t run, giving me, at different attempts, different error messages. In the time since then, I have read many suggestions from many different websites and I have tried some of these suggestions, all with no success – until today. I have just completed the suggestions made on https://support.mozilla.org/en-US/questions/1327628 and Firefox is now back, working. I am happy and grateful, but not finished. None of my personal data came with the currently functioning version of Firefox. Since the re-emergence of Firefox, I have been reading several websites dealing with copy, backup and restore of my Firefox profile. Right now, the path C:\Users\rsuth\AppData\Roaming\Mozilla\Firefox\Profiles\ shows 5 folders: Two of the folders show 11/11/24 as the date modified (probably the date of the download from Mozilla). The folder 0dppjrfa.default contains one file, times.json, dated 8/11/2020. The other folder, ru82tlj5.default-release, has 97 items, most dated 11/11/2024. The remaining three folders are all dated 12/2/24 (today, as I write this). One folder’s name ends .default, the second name ends .default-release, and the third name ends .default-release-thirteen digits. The question that I am asking here is what do I do next to, hopefully, bring back the personal date I had with Firefox before my updating to Windows 11. Should I delete the folders dated 12/2/24? What, if anything, is the significance of the folder whose name ends in 13 digits? I’m hoping someone will be able to tell me how to fix these Firefox problems. And if I can, then I hope to be able to do something similar to help me bring back Thunderbird as well. Thunderbird became unfunctioning at the same time as Firefox. Thank you.

Hi. I'm trying to troubleshoot failure to resume a download in Firefox and I want to see the HTTP headers just like in Network Tab of Dev Tools, but I can't find how to open Network Tab from the "Downloads" list. Is it even possible?

As the title states, certain media elements within Firefox refuse to play with audio, but only with frustrating inconsistency. For example, any videos on Youtube are fine. Any videos on Reddit are fine. But many videos, most commonly on boorus and streaming sites I cannot name here, will not play. The volume on the video slider is all the way up, the Firefox application is not muted, the site is not muted, and the tab is not muted. The only thing that makes those videos play audio is if I left click on them to open them in another tab by themselves. While it solves the issue, it's still an extremely inconvenient way to go about my browsing. I know for a fact that this is a Firefox problem because those same videos on those same sites work perfectly fine within other browsers. Please, does anybody know of a solution to this issue?

Today when I launched the browser, a sidebar appeared. No matter what I tried, I can't remove it, it really gets in the way, I searched for information all over the Internet, but I still couldn't find any information. How can I remove the sidebar?

I am trying to set the default Map application to Google Maps, which is the best. Apple is the worst. I like the Duck Duck, and want to keep it, but this map problem doesn't even allow Google Maps to appear in the search results!

This is an hard problem for me -- Apple sold out a long time ago and offer an inferior app.

Is there any solution?

BTW, I NEVER SUBMIT! I SEND.

I love Firefox, I use it on all my devices. And daily I access facebook.com on this browser, it's been working flawlessly - until yesterday. Yesterday, using Firefox (ver 130.0.1) on my Windows 10 PC, I tried accessing a FB page which I visit sometimes: https://www.facebook.com/OpenOscillator

Rather than reaching that page, I got a white screen with this error message: "Sorry, something went wrong." And since then, even visiting the Facebook home page (or any other FB page) has the same error message.

Today I tried the same thing on my Mac (OS 14.3), using Firefox and logging into facebook.com, which worked as usual. But when I went to https://www.facebook.com/OpenOscillator, I got the same error message: "Sorry, something went wrong." And as happened on my PC, now on my Mac I can't access any FB page on Firefox.

And just to mention, I've rebooted both the PC and the Mac, yet this problem persists on both devices.

Trying this same exercise on Edge on my PC does not have this problem. Nor does it happen when doing this on Safari on my Mac.

So, this problem has only been happening on Firefox. I can no longer access facebook.com with Firefox. Do you guys have any ideas how to solve this?

Helpful to know: Do you have the same outcome if you visit this FB page: https://www.facebook.com/OpenOscillator

Thanks for your assistance! Steven

bsky.app cookie continues to be loaded on computer even after I continually delete it, privacy set to strict and blocked under "managed exceptions, why is it being reloaded when I don't access the site. None of the sites I access are linked to it, only visited once and if this alternative to x continues to set cookies, how can I permanently block it, thought the exceptions list was supposed to keep blocking it. So far it's come back three times, I'll screenshot it next time and attach.

For the past few weeks when I click into the URL address bar, I get a popup window covering the entire Firefox window (see screenshot). This is really annoying, as I have to escape out of this to get back to the window. It makes more sense just to place the cursor in the URL. Is there a way to disable this? Or is this a bug? Or is it a problem in my installation? I'm running Firefox 133.0 (64-bit). Thank you.

Since the 133 upgrade, some sites don't show scrollbar anymore (and therefore scrollwheel also doesn't work.) Is this a setting? (very annoying...) Windows10/64bit version.

My computer died about three days ago, and firefox had three windows open. When I rebooted the computer again, firefox automatically started up, and the flyout panel thing that shows up when you right click on an app claimed that all three windows returned. However, only two of them were actually accessible, and clicking on the app to move between them and the F3 window confirmed this. Clicking on the third window accomplishes nothing, reveals nothing, and just moves the little checkmark around in that flyout panel. Closing the other two windows before restarting firefox does not open a new window because it thinks one is already there, but I cannot in any way see or access it outside of its label in the flyout panel. Even hitting "Show All Windows" just shows the window I am typing this in. What am I supposed to do here?

Helllllllllllp! Just had firefox install an update & now all my saved bookmarks, login passwords & previous home page have all gone. Have reset Home page, checked that Profile is correct & the bookmark folder is empty. Where have they all gone. Yes I have restarted my computer but made no difference.

From last 2 days the website's specific product page https://hassan-brothers.ae/product/thermal-rolls-80-x-80mm-receipt-paper-48gsm/ continuously showing "refused to connect". as a developer I had to manage and add products for my client but unfortunately this problem occurs. I contacted to the hosting provider they said "I think some kind of sql query issue" after working on SQL it's working on other's end but still I unable to access.

Kindly resolve my issue thank you. I urgently need this.

Firefox Nightly 135.0a1 - Debian APT repository

I searched around DDG for awhile and didn't seem to find others with this issue. I have Firefox-esr installed on another device and the option is still enabled over there. Is there a way I can gain that back on this install? I use it for every link I copy. Thanks

Hello, At one time I could login at home to view my Spectrum.net account on Firefox (default browser), now I get a popup which reads "This feature is currently unavailable. Please try again from home or contact us for assistance. "IDID-4000"

I get the same message on my laptop and desktop, both running Firefox. I can switch to the Edge browser and login with no issues. I have cleared cookies and used other suggestions I have read on the web, but to no avail. Any help would be appreciated!

Thanks! Tony

I met the same issue with https://stackoverflow.com/questions/27514404/web-worker-blocked-by-main-thread-in-chrome . It was asked 10 years ago and I learnt that it was fixed in chrome via https://issues.chromium.org/issues/40398809 . Is it a bug for firefox? Is there any way to work around? Thanks.

Since updating Firefox I can no longer connect to known good sites without getting "Did Not Connect: Potential Security Issue".

This includes U.S. government sites! For instance, try connecting to https://covidtests.gov/ .

Why completely block access to the site? Why can't I make exceptions or tell Firefox to accept the risk and continue?

How do I turn this odd feature that dims FF bars when window loses focus? As of look of it only tabbar and toolbar are affected. I couldn't find anything relevant under "about:config". Also some tricks with CSS didn't work for me, maybe because I have custom chromeCSS that brings tabbar under bookmarksbar and applies other customization so that FF window looks like old good FF before they started to put everything on a single line in the bar. Thanks in advance.
