When I navigate to a YouTube video, I get the word YouTube in giant font as shown in the attached screenshot. There is some gibberish along the left edge. Actually, when I navigate to a specific YouTube video, I watch the correct video show up normally for about 1/2 of a second and then it immediately converts to the attached screenshot.

 This does not happen with Safari, and it just suddenly started happening today with Firefox. My guess is that a setting suddenly got changed by accident. But there may have been an upgrade that does not work on my computer. 
 Any suggestions or ideas for further troubleshooting would be welcome.

Recently I have been unable to sign in on several different sites, but have had no problem on others. This is a new computer with Windows 11, and I set it up about a week ago. When I tried to purchase a You Tube TV subscription, the purchase locked up. I tired it with Chrome and no problem. When I tried to log into my credit card account with Chase, I got an error message suggesting I try later or use another browser. Again Chrome worked. Then I tried to log into Aflac and got a message saying the site wasn't redirecting properly. Again Chrome worked. Also Firefox worked for Aflac on an older computer.

I don't want to use Chrome. Can anyone help? Andy

For quite some time (months), the Alarm.com web page has not worked properly. I get the message "Oops...Something went wrong.

Don't worry your system is fine; it's just an internet thing."

Refresh does NOT solve the problem. Today I resorted to using Edge, and all worked well. It's clearly a Firefox problem. Can you tell me what's going on? Is there a fix? I'm disappointed that Firefox can't deal with a web page.

When I click submit on a form and switch tabs before it completes processing and return to the tab after the page is not refreshed with the new page returned from the server. However, the action has completed on the server. This only started happening in the last couple of weeks. Note: if I stay on the tab without switching it is fine.

The Picture in Picture feature does not work with Hulu. The picture pops out but it remains stuck into the Hulu tab. It does not float around. So it does not operate like intended. The black box is the pop out. when viewing it does have the picture. You just have to view it on the tab Hulu is opened on. Any ideas? m

This is the error message I get when I try to connect to different sites:

I want to copy/clone information in my Firefox Profile (Bookmarks, Logins, ..) from one device to another. Once that was accomplished, then I would enable Firefox Sync for the two devices.

Scenario: Device “A” (Profile A): Primary/Original/Source Device “B” (Profile B): Copy/Clone/Duplicate

I understand that if I set up Firefox Sync first and then sync the two devices what I will get is a combination/fusion of the information on the 2 devices, i.e., all the “good” stuff in Profile A plus all the superfluous stuff in Profile B that I would just as soon ignore/delete – which is not what I want. This issue has been raised in a number of other posts on this forum but with no suitable resolution offered (that I could find). I’m wondering if there might be a “work-around” that would achieve the desired result.

So ... would this work?

1) Back everything up first (of course!) 2) Glean any unique information to be preserved (Logins, etc.) from Profile B and incorporate it into Profile A (Profile A now has everything essential!) 3) Purge Profile B

   a) Create a New Profile on Device B (and delete old?)
   b) Delete everything possible from the new Profile B (default bookmarks, etc.)

4) Login to Mozilla account and enable Sync

The idea is to create a “blank” Profile on Device B so that when Profile A and Profile B are Synched together (combined), Profile A remains unchanged, and Profile B is populated with everything in Profile A (a perfect copy!). The result that I want after Sync is essentially A+B=A, the solution of which is of course B=0, hence the focus on creating a "blank" Profile B.

Instead of purging Profile B as above, an alternate method might be to first “pre-load” Bookmarks in Profile B by the usual method of Backing up Profile A Bookmarks and then Restoring them to Profile B. At this point Profile A and Profile B Bookmarks would be exactly the same and Synching the two devices should make no changes to either’s Bookmarks. Logins and other information would still have to be purged, but this could at least be a head start.

Presumably this idea could be extended to more than 2 devices (but with only one being the “Primary”).

Note that I am (myself) only concerned about Bookmarks and Logins, and am thus glossing-over how other information that might be important to others (Browsing History, Tabs, etc.) might be Synched.

Could someone from Mozilla/Firefox with a knowledge of the inner workings of these features please comment as to the efficacy of this “work-around”?

Thanks.

I signed in to be sure to save my bookmarks and i lost them instead. When i hit sync, i wanted to backup my current bookmarks. Instead, I lost them. It reverted to the old bookmarks i had a few weeks ago. I lost all of my bookmarks from the last few weeks. HELP!

I don't know where to add shortcuts all at once instead of adding each one individually, I tried to search for a "shortcut folder" within the bookmarks manager and i found nothing, is there anything I can do to move opera browser's speed dial bookmarks into firefox shortcut

When trying to open sites from my email, such as usps.com, I get the following message and it will not allow me to open it even if I put the address in myself:

Hmm. We’re having trouble finding that site.

We can’t connect to the server at tools.usps.com.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

PLEASE help me find this problem. Until the last update, I didn't have this problem. What do I need to do? Thank you

Unable to view YouTube comments using Firefox on android. I can view the comments on Opera, duckgo and chrome.

This problem started about four days ago. Comments show on the short videos but not the regular videos. When I tap on "comments" the resulting page/frame is empty.
