Hello, I am running Firefox on a W10-Pro PC. I always click the lock to check certificate validation. In the last month I keep seeing "Connection verified by a certificate issuer that is not recognized by Mozilla".

When I click for more information I see that "Norton Web/Mail Shield" does not recognize the certificate issuer. When I click on Learn More it takes me to a Firefox site "How to disable the Enterprise Roots preference" I also checked W10 certmgr.msc and I see Norton is listed. Images included below. I would love to resolve this issue. Thank you for your time.

Firefox consumes almost 2Gb of RAM with only one tab open. I find this surprising, and it's a major performance issue for me.

Do you have an explanation or solutions to reduce this memory overconsumption?

Hi all,

Since recently Firefox keeps redirecting me as if I'm in Switzerland where I haven't been to ever since I use the internet. My location is in Croatia. I have tried to clear cache, cookies and browsing history multiple times, use incognito mode, my language is setup to English and I don't use VPN. Nothing helped. This unfortunately requires deeper dive because I can say for certainty that an individual who illegally surveils my device deliberately made this change and something needs to be done on Mozilla's end. Is there a way to directly contact Mozilla's support or what would you suggest to do to solve this issue?

Many thanks,

Lana

The thumbnails can be momentarily seen but within less than a second they disappear. Not happening in edge so doesn't seem to be a computer setting. Cleared all cookies and cache in firefox. No different. The attached image shows the pictures that are missing in firefox. Image taken from an Edge search.

Thank you in anticipation. Steve Balderson

Hello

I reinstalled windows 10 on my laptop with keeping my personal files intact. During the installation process Firefox was removed. After Windows was back I reinstalled Firefox and it works just fine except none of the old information, passwords, bookmarks etc are there and I tried just about everything to retrieve them but no luck. I tried to bring up profiles but only the new one was listed as default. What can I do? Thanks for your help.

Hello,

after update of window 11 to 24H2, Firefox keeps crashing on start. I completed deinstalled Firefox, rebooted and installed again, no effect. I switched off hardware acceleration and all add-ins and selected system theme, no effect. No crash occurs when started in troubleshoot mode. I did a clean-up (in troubleshoot mode), no effect. What should I do now? Where is the error log?

Regards Christian

Hi, I accidentally did a refresh on my Firefox (Win 11) and therefore I now have an "Old Firefox Data" folder on my desktop and Firefox is completely almost back to stock.

I have lost all extensions, customizations, settings and other configurations. Luckily, I had taken a backup of my bookmarks prior to doing this.

How do I return everything (including extensions) back to pre-refresh state?

Thank you.

i had setup a new windows and when i tried to sync my Firefox data i found nothing and all my bookmarks and passwords was lost.

i need you support to recover my data.

I'm trying to measure power consumption in Firefox using automation. My goal is to get power consumption metrics for specific webpage loads.

What I've tried: 1. Using Puppeteer with Firefox's profiler:

  - Enabled power profiling preferences
  - Used the Profiler CDP commands
  - Got profile data but no power metrics

I know Firefox DevTools has power profiling capabilities in the Performance panel, but I need to access this programmatically. Is there a way to: 1. Access the same power metrics that Firefox's Performance panel shows? 2. Get power consumption data through Firefox's debugging protocol or any other API? 3. Enable and collect power profiling data in an automated way?

Any guidance on the correct approach would be greatly appreciated!

When playing videos in Facebook after a few of them I get a blue circle spinning . When I use chrome I don't have a problem.I have had Firefox for over 10 years ,if I cannot fix this Em going to have to use chrome

A few months ago after an update to Firefox the window would open but be transparent with no controls visible. I tried the refresh Firefox option which worked but left other problems. A website has a medium blue header at the top with white fonts (links) on it, which still appear that way in Chrome and Opera, but since the refresh the header is black with black fonts in Firefox (which of course you can't see). There are also variations of this problem on some other other websites. The only way I can see links on those sites is to set color management to override 'always'. Is there any way to fix this problem? Thanks Mike

I've used Norton Safe Search on FireFox for years with no problem. But few weeks back, when I use Safe Search, it does no longer brings back the green checks indicating the site is safe. It works with Edge, but not with FireFox. I've contacted Norton and still waiting to get a response. Anyone have idea as to what is going on and how to fix it?

thanks -

Hi, I'm having issues because I don't seem to have fully migrated from my old version of Firefox to the new one installed by auto update. The two versions are running in parallel causing some major conflicts and incompatibilities, e.g. my open tabs are not showing in the new version (even though I've tried to update my Profile:default), it's not interfacing with my password manager app, links are opening in the new version. I'd be really grateful to know how I can resolve this (please note that I'm not a technically advanced user).

I love Firefox, but I can't find an answer to why the keyboard input lags 5-10 seconds. This is always noticeable in NYT Games like Wordle, but not Bluesky, for instance. I use Chrome now for NYT but eventually I'll go back to stay if I can't fix this, which is a shame as it's the best browser around. Thank you for your help.

Hi there,

Our website is not showing to our customers and they are receiveing this error MOZILLA_PKIX_ERROR_OCSP_RESPONSE_FOR_CERT_MISSING

We have checked our site with SSL Labs https://www.ssllabs.com/ssltest/analyze.html?d=locomotivestation.com.au and it returns showing the SSL is fine.

We can see the site and operate on Google Chrome but cannot work out why it is not displaying on Firefox.

Any suggestions?

Thanks
