Firefox Support Forum

FireFox assumes that text size is the same for all pages in a domain, rferl.org for example. That is _not_ true. If I have set size to 50% and then take a link to a page that's different and have to set size to 67% to read it, when I return to the original page, size is 67% and text is too large.

i cant get firefox to open main page no matter what i try. Ive download it a few times and then it ask me to no let it fix it i did and then it still wont open.use firefox more than any site. ty if you can help.

Dear fellows,

I did lost all history data after a previous update, my user got corrupted data and somehow I did manage to import the info into Edge browser. To my surprise after I reinstalled a clean Firefox, it only imported back 3 months of browsing history. Topically, average user keep a computer 3-4 years.. I don't know from where developers came with the idea of limiting to such a shot interval. I have thousands of browsing history links from more that 10 years kept and I need them all.

Tried to increase the number from about:config, but there is an option only for Chrome which I never used and always hate :)

I did installed Chrome to convince myself about it's ingenuity, even if it was not necessary. It does have import option only from Microsoft Explorer, no Edge.

If there is a solution for importing a longer period and high number of entries, please share it.

I'm not an IT expert, but I can manage consoles if there is an even deeper option to modify config files.

Thank you in advance!

I've been using a Rewards site regularly (3/4 times per month) for several years without problem. This weekend the attached pop-up appeared. It makes no difference whether I select Resend or Cancel, the program just re-displays the pop-up trapping me in an endless loop. The only exit is to close the window and abort the process. I was able to complete the task without any problem using Edge instead so it appears to be a Firefox specific issue. I haven't consciously changed anything since last using the site successfully on 24 May. Any help/suggestions appreciated.

The Find in Page feature is not working in my build of Firefox Nightly. Application Basics

Hello everyone! I have a really nasty problem (for almost 3 years now) that I just can't get a handle on (and I don't know the root cause 100% either). Here's my situation:

• We have a self-check-in terminal (kiosk) that is used in hotels
• The terminal runs a web app in FF full-screen kiosk mode (-kiosk flag)
• 99% of the time everything works fine and without any problems
• Sometimes though, the problem occurs that the entire browser content no longer responds to touch events
• My app continues to run, we see the visual feedback from the touch monitor, but Firefox no longer responds to anything
• If you connect via AnyDesk (our remote maintenance tool), you can click with the mouse
• Even the DevTools don't respond to touch interactions
• As I said, everything is fine via mouse interaction (remote)

What I have already tried:

• Disable hardware acceleration
• Browser restart every day at 4:00AM (so far so good, but it still happens sometimes in between of these restart windows)
• Set the widget.windows.window_occlusion_tracking.enabled to "disabled" - I read that the problem could be related to that

Does anyone know the problem and can help me? It's really critical for our business, as the guest cannot interact with the device and only a browser restart helps.

One more thing: I saw today that a second Firefox.exe process was running. After killing it, it worked again. What kind of process could it be that is affecting the main app so much?

THANK YOU

This pops up every few hours. Sometimes it pops up invisible but steals focus from the main window. How can this be disabled?

I tried all methods that have been mentioned everywhere on the Internet, including policy.json, Group Policy on Windows, etc. Nothing disables this nagging yet.

When I try to open a what may be a link in a page, which should bring up a PDF file, I think, I get the following:

Firefox Can’t Open This Page

To protect your security, api.medicare.gov will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.

When I click on the Open Site in new Window button I get a new window with the following:

message "Unauthorized" context {} code null

I'm hoping to get some help with disabling the Insecure connection password warning in Firefox version 115.11.0.

In previous versions, I could disable this warning through the about:config settings. However, I couldn't find the specific setting (security.insecure_field_warning.contextual.enabled) that was mentioned in some online resources.

I understand the security risks involved in disabling these warnings, and I only intend to do this on a trusted website on my local network.

Could you please advise on the best approach for achieving this in Firefox 115.11.0, or any alternative solutions to manage insecure connection warnings for trusted local sites?

Thanks in advance for your help!

Hi, so sorry for the delay and inconvenience caused by this matter, I’m new to all of this and not sure what I did or have done to create this giant mess I have for myself, but I need some help! Seems that my computer doesn’t work correctly anymore, nor do my phone's. Somehow I joined this and need to fix everything. Thanks for your help!

In Firefox, whenever I go to nab.com.au and then click on Login on the top right, I hear a constant stream of static noise coming out of the speakers.

In Chrome, when I just visit nab.com.au that same noise starts.

I have a set of Bose speakers connected via an optical cable.

This behaviour doesn't happen on all sites. Just some. As soon as you close the tab, the noise goes away.

It's driving me absolutely nuts.

Hi Forefox dosent show cookie content pop ups for some webpages. Have tried loading the same webpages with Edge, and a pop up is shown, whwere i am asked which cookies i would allow.

Have cleared the cahe/cookie, started up in secured mode, deleted profiles (made an search on firefox/Mozilla and deleted all files) and reinstalled firefox but the problem persist.

It started a month ago, just like that, Have changed pc, to a new one, and from windows 10 to windows 11, still the same.

Help would be nice, thank you.

I am trying to add an mp4 video to my website using the following code:

<video width="320" height="240" controls>
  <source src="images/###.mp4" type="video/mp4">
</video>

where ### is the name of the video file. I get the following error message:

"No video with supported format or MIME type found."

In the console the following is displayed:

"Media resource http://127.0.0.1:5502/images/###.mp4 could not be decoded. video.html All candidate resources failed to load. Media load paused. video.html Media resource http://127.0.0.1:5502/images/###.mp4 could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_METADATA_ERR (0x806e0006)"

Runs just fine in Chrome and I have no pop-up blockers installed. Autoplay is set to be allowed for all websites.

Windows 11 version 23H2. Firefox version: 126.0 (64-bit)

My PC froze and had no choice but to reload win 10. After doing so I had the choice to download win 11 for free which I did. When I download Firefox all of my bookmarks were missing. I have tried to follow your instructions to retrieve them i.e. Troubleshooting... Application Basics ... Profile Folder...Open Folder... which opened >>> C:\Users\AppData\Roaming\Mozilla\Firefox\Profiles\42o9xo83.default-release . Sadly, I am not a Teckie and I do not have a clue what the next move is to get my bookmarks back.

Can you please help me to get my bookmarks back. Thank you MM

PS... (I have deleted my username for security)

I have used Firefox for Windows for many years and have had no problems until recently. I have been unable to print my emails: when I click on the printer icon in the upper right corner of an email nothing happens. I was wondering if there was something in the settings that was causing this problem. Thank you!

hello,when i download my attached files in mailbox(mail.xmvds.com), it can be everytime warnning me ,but i trust this url ,it is my company's office mailbox ,how can it unblock it ,?

I cannot begin to express how frustrating this change is... and I struggle to comprehend why anyone would introduce this by writing it into software, but I'm sure it has something to do with money and profits.

There was a time when you could do a search and get a list of results, and then view a specific listing, and then return to your search page and view another listing. however, those days are evidently gone, as now when you return to your search page, it's slightly different results in a different order. Most are there, but some are missing entirely, and the ones that remain are varied slightly. Whaaaat for!? It is truly a form of torture.

Now in fairness I can't tell if it's the browser (Firefox), or the search engine (Duck Duck Go), because I am unfortunately not a developer. However, whatever is causing it should be fixed out of a sense of social responsibility to the greater good.

If anyone knows why this happens and knows how to fix it, I would be sincerely grateful if you shared the solution.

I have installed firefox in my laptop for years. after latest update, firefox runs just fine only for the 1st time, then after closing the app / restarting the laptop, firefox keep giving error (attached) I have tried to refresh, run troubleshoot mode, uninstall and reinstall again at one point I was able to recreate the issue only after reinstalling firefox 126.0.1 portable version and then syncing to the profile ( run ok for 1st time, then it broke down after closing it) The problem also seems repeatable using firefox 115 protable Now, I tried to reinstall the portable version from scratch, it keeps hitting same error from 1st run

I have also double check the firewall and antivirus to make its not blocking All other browsers works just fine
