Hey all. Please help.

Periodically I delete my cookies and site data thus... Preferences/Privacy & Security/Cookies and Site Data/Clear Data. I used to use an add on for this but it stopped working.

Today it says I have "Temporary and cached files 1.3 MB". But it says that after Clear Data. It says it after I quit and restart Firefox. And I still says it after restart the computer. My Manage Data... and Manage Exceptions... boxes are empty. I have tried running Antivirus Zap Pro, which doesn't find anything sinister. How can I get rid of it... whatever it is? Can I access the folder and delete it manually?

I'm on an old Macbook Air, running Monterey. With the latest Firefox 132.0.2

Thanks in advance.

I have just installed "Opera" browser which I thought would allow me to install an App called "Marine Traffic" onto my computer. It seemed to make changes to my default browser which is Firefox, so I re-installed Firefox. Now when I click on Firefox it comes up with a search bar but it is not the usual search bar but a largely blank screen with just a search bar in the middle. It does come up with an option at the top for another search session and when I click on that it is the normal Firefox browser screen. Can I get rid of this first strange blank screen with search bar? Mark

Hi, I just installed Windows 11, version 24H2 and now in Firefox I'm continually prompted with "Awaiting Location Permission, Grant Firefox location permission in system settings".

The problem that location has been turned off by admin on this computer. How can I stop these continual prompts from Firefox? I have checked the box in Settings to block location requests from new websites but am still getting the prompts.

Thank you.

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
