I've seen a few submissions describing the same or similar issues, but is there a consistent, effective way of changing the time zone in Firefox? It keeps defaulting to the wrong time zone (despite everything else on my system displaying the correct time zone) and has been doing so for weeks. Solutions appreciated!

https:\\archive.org works perfectly in Firefox on Win-10, but on a new Linux Mint install, (with default Firefox as included), this particular website simply displays as a blank white screen. Every other website I try on the Linux install works perfectly; it is only this one website which does not work.

There are no add-ons, no proxies, no security suites, nothing extra. I cleared all cookies and cache. Tried running FF in Protected Mode. Nothing seems to fix it.  There are no error messages displayed - just a blank white screen.

And, to make it worse, I am not particularly computer-literate, (I'm 82 years old...), so you will have to give me simple guidance if I need to get involved with deeper logging etc.

I have been using Firefox for years without any problem but 126.0.1 (64-bit) is making me to consider stopping it. I am having issues playing live cams, getting some websites running properly, authentication issues, etc...etc..

Why?

I have received two emails from Sky regarding updating my Sky ID on my iPhone to enable continuing use of Yahoo emails. However, when I click on the link given there is a Google error message denying access owing to a violation of Terms of Service. This means I am unable to update and could have future problems with access to Yahoo emails on my iPhone. Can you help? Alan Warburton.

Hello,

I am experiencing an issue related to the Vanguard anti-cheat system used by Riot Games, specifically in relation to League of Legends. After installing the game and Vanguard, I am unable to open Firefox. When I try to launch Firefox, nothing happens. However, if I change the name of the firefox.exe file, I can start Firefox on a different profile, but it only works for a short period before becoming unresponsive. None of the options or tabs respond after that.

Could you please provide assistance on how to resolve this issue?

Thank you.

Hello,

My password saved are deleted every time I close FF. It used to be manageable because Google and other sites didn't require me to fill my passwords (cookies did the trick I suppose) but now I also loose access to gmail and Youtube every time I close FF. It's annoying to have to use 2FA every damn time. And keeping the passwords available.

I've tried every answer I found by looking around :

- tried to start in safe mode - disable hardware acceleration - I have no extensions

FF saves the passwords correctly (at least they appear in the saved password tab) but they are erased every time I restart FF. The cookies aren't automatically deleted (FF remembers my browsing history) but I need to relog into Google.

I getting frustrated.

the only autoplay setting i can find is under privacy and security. the page shows DEFAULT FOR ALL WEBSITES: Block Audio and Video, but videos still open and play. the page does not retain the change when i select the button REMOVE ALL WEBSITES. this problem has not been happening for years. it may have begun about six months ago. thank you for your time

Lately, I have been getting a pop-up error when I start and close Firefox. The error reads: "XULRunner Could not determine any profile running in backgroundtask mode!"

I have found posts such as this one: https://support.mozilla.org/en-US/questions/1398228 and other posts suggesting to disable the scheduled task in Windows Task Scheduler, but none of the solutions have worked thus far. Anyone know of any other solutions?

After update, when I click on auto fill option a settings tab opens every single time. I close it and it happens again. I use firefox to fill out some repeated forms (and separate topic would also like to customize these autofils and pre-write some ideally), but this is a new problem that breaks using firefox totally for me, causing lots of scrolling clicks and time wastage. What changed that can be fixed in recent updates on this? Thanks.

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.

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.

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.

Learn more…

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

message "Unauthorized" context {} code null

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)
