Firefox Community Forum

My Firefox browser has been crashing for a while now (Years). It's fine playing YouTube and BBC iPlayer but when I advance the time marker to a different part of the stream or video, it crashes. It also has a problem when playing slots. It seems to crash a lot making it impossible to play.

I have tried using Firefox in Troubleshooting Mode but the same things happen.

Here's the crash report ID

Many thanks in anticipation and I hope someone can help me fix these issues.

I am trying to access the link "https://www.sorn.service.gov.uk/". This is the address of a click through from the webpage "https://www.gov.uk/make-a-sorn".

I keep getting this error:

I am on Windows 10 Pro 22H2 19045.5011, using Firefox 132 (64-bit), not running Kaspersky, I do have AdGuard (7.19.0 (4853) (CL 1.16.44, DL 2.5.41 )) and Malwarebytes (4.6.17.334) on my system along with their browser adons. I have attached some screenshots, hope they are useful.

Please help.

When attempting to drag/Insert picture into email text, the message "The following files couldn't be attached: filename.jpg. Please try again later." appears. I have not been able to find a solution. The dragged/Inserted picture always ends up outside the email text box and cannot be moved into it. What is a solution?

Is this something new or do I need to reload Firefox? Firefox 133.03 64-bit is up to date on Windows 10.

It worked last Christmas!!! It is not important now that the holiday is over but would like to fix it.

Hi,

I have an odd problem with a friend's Firefox and Thunderbird on Windows. The font changed to white in the address bar, the tab titles, some content on websites, some elements of the settings etc.

From what I can see there is no difference to my settings under "Language and Appearance". When I create a new profile either with the profile manager in Firefox or by renaming "%appdata"\Mozilla Firefox", nothing changes. So I can rule out a custom userchrome.css or similar in the profile folder. When I switch to "troubleshoot mode" with the old or the new profile, everything looks fine.

It also affects Thunderbird, but no other programms.

I can't figure out, where the problem lies.

I cannot access my Coventry Building Society account online using Firefox. The building society says it is is due to a recent Firefox update being insecure. Can Firefox fix this?!

When I logged into my laptop on 9th November Firefox had closed. This happens sometimes, I'm often not sure why, but this time the previous session didn't automatically repopulate when I restarted. I navigated to the history options with the idea of retoring the previous session - either using that functionality or individually opening previous windows - but history was blank and the previous windows option was greyed out. Following suggestions online I've looked for .bak or .json or similar files to use as restore points but there's nothing since much earlier in the year up to 8th November, which are pretty much empty, and the 9th.

I'd be very grateful for any suggestions!

Hi, i wanted to see a Movie on WOW TV but only have a blank Window in my Browser. This Problem is only with WOW TV. Amazon Prime and Netflix Stream works perfect. The Support from WOW TV has no solution for me. They only have one hint for me to use Chrome or Edge.

Within the last week, my homepage has changed in look and operation. It no longer has all of my bookmarks, I can no longer navigate back to my homepage from other sites, etc. Also, it have a very plain, sterile display. What changed and how to I get back to my original homepage?

Dear Firefox Support,

I am experiencing an issue with YouTube and some other websites not loading properly in Firefox. The sites continuously try to load but never fully display. I've attached a video link demonstrating the problem for reference: Video Link Video Link.

Could you please look into this issue? I’ve tried clearing the cache and disabling extensions, but the problem persists.

Thank you for your support.

Best regards,

I received a Mozilla Firefox (64) update notice going for version 132. When it didn't complete, I checked that my version is Firefox ESR115 (115.17.0), which operates with Windows 7-8.1. I have Windows 10, which matches with your version 132. So my question is how do I change/update my Firefox over to match up with Windows 10 and the Version 132 update?

Every time I try to view a pdf file on Firefox I can view the file but in the lower right 1/4 of the screen I get a graphic of a page with shaded areas representing lines with writing on them. There is a type of pen cursor moving along the line.

This happens with different pdfs - from the internet and from my saved files. This doesn't happen on another computer with Firefox.

I've deleted and redownloaded Firefox an number of times, also tried troubleshoot mode - no improvement. Virus scanned, restarted a number of times.

Pdfs work on edge and chrome and reader with no problem.

I have a screenshot.

Any Ideas? Thanks

Hi, In the last hour FF has stopped working completely. I made the mistake of using Ccleaner, which is probably the problem, I haven't had issues cleaning before, though I usually check the registry before deleting and don't recall seeing any entry for Mozilla (I may be wrong, though).

Firefox was working fine a couple of hours ago, but now it won't open at all, except in admin mode and then it won't open any links or tabs, not even settings. I've uninstalled FF, deleted the folder in the Programs folder, and reinstalled it from scratch, but there is no change (the one difference is that it wouldn't open in Admin after before I reinstalled it). Waterfox doesn't open either, but Thunderbird seems to work with no problems.

Thanks, Matt

When I try to sign into eBay, a multi-photo comes up asking me to identify like objects in order to be allowed to enter the program. I believe Firefox is causing this problem. How can I fix the problem?

You Tube will not go full screen. I've tried reinstalling, clearing cache, refreshing page, pressing F11. Nothing works. It will go full screen in a private browser, but not in a normal one.

The icons on my home page suddenly became significantly reduced in size. Sure, I can tell what they are, and I've increased the text size for their identifiers below the icons. But they are now so small as to be not pleasing to the eye. How can I put them back the way they wuz?

The extension ZoneAlarm Web Secure is preventing safe downloads from web sites. I do not want this program in my version of Firefox. version of Firefox. There is no way I have found to remove this program. Please advise me how to do so.
