Firefox Support Forum

Sometimes I find that Firefox just randomly closes on my laptop, usually when I step away for about 10-20 minutes. I can't find any info in the about:crashes page when it happens.

Hi everyone,

I'm running Firefox which I compiled with vaapi support because I was trying to use hardware acceleration for videos, so I think this bug may have something to do with that. Every time I open a pdf file my browser instantly crashes. When I use troubleshoot mode I have no such issue. I then tried with a fresh all-default user profile with no add-ons, nothing, and still I crash when loading a PDF. Any pointers would be appreciated.

https://tasmota.github.io/install/ This is an example of what i am tryingto achieve bit no matter on which site i am , i do not get to choose from ports and my devices and always faults out saying similar messages that the browser does not support web serial in one way or the other for any site doing similar task. error message is as shown in the image shared basically complains of browser not supporting web serial.

Firefox can take screenshots of pages or screenshots of custom areas of pages.

According to the documentation, when we download the image, the filename should follow the pattern: Screen Shot yyy-mm-dd at hh.mm.ss.png. If I use the :screenshot at the console, the pattern works as documented.

But Firefox is using a different pattern when I choose Take Screenshot from the context menu. The pattern includes the page's title. Example: Screenshot 2024-04-14 at 18-35-16 General ‹ Settings ‹ Geomaster Lda — WordPress.png.

Since the page title can have non common filename characters, I have problems with such filenames. My uploads to MediaWiki fails with such filenames. I know I can report or improve MediaWiki, but my question here is quite simple.

Can I change the Firefox's default pattern for Take Screenshot's downloads?

Help! I updated and now all my tabs are crashing and I'm on a deadline! I tried to rollback but couldn't find the exe. Here are the last 5 crashes:

Many thanks,

Hello, By default, DoH fails on Max Protection in the latest OS versions listed above. The workaround I've discovered is using https://1.1.1.1/dns-query, but I would rather use the default settings.

Hi Friends.... This morning logged into my website as usual and this message appeared on the home page. I have not checked the link as it seems potentially malicious ... It does not appear when visiting my site on Safari. I have emptied the cache I have been through troupbleshooting mode I have reinstalled Firefox and it still is there..

How to rid myself of this

All help gratefully received Graham

Is there a way to turn off tracking URL fragment insertion from the release notes page when clicking "What's New" in the Firefox update modal?

When I click "What's New" in this modal (see Screenshot 1), it loads the release notes page for my current version (although it really should load the release notes page for the version it wants me to upgrade to, but that's another issue altogether), and inserts a bunch of tracking URI fragments onto the URL (see Screenshot 2).

Is there a way (in Settings, about:config, Windows Registry, etc.) to disable that fragment insertion?

Yesterday on my linux computer I noticed that my container setup ise back to the default setting. Now I'm using my windows laptop, and it is als back to the defaults. I'm afraid the same thing will happen when I start using my windows desktop. Should I poll the network cable and delete my firefox sync data, so I can hopefully save my containers setup? Or is this not going to help, and I'm fucked anyway :)

Hi there, thanks for your attention I'm a web developer and new to using firefox. I was using chrome for years and now just because firefox on android let's us install add-on like it's desktop version I'm switching to firefox. as a developer I need to learn about the features firefox offers to developers or ask for any features that are missing right now, so my current issue is about the pictures I will attach. I want to have more information about the element that I'm inspecting right in the tool-tip over it for example it's active font-family or things like that. It took me sometime to figure out how to find the active font of the target element thanks to This post. but in chrome it's showed in the tool-tip.

Merhaba

İnternet üzerinden yaptığım alışverişlerde ödeme sayfası bölümünde beyaz sayfada kalmaktadır, java devreye girmeyip ödeme bölümünü onay sayfasına yönlendirme yapmıyor beyaz sayfa olarak kalıyor.

mecburi bu durumlarda başka tarayıcı üzerinden girip yapmak zorunda kalıyorum.

bu konuda yardımcı olursanız sevinirim yoksa sevdigim tarayıcmı değiştirmek zorunda kalacagım

It looks as though installing this 115.10 ESR will be a "new Install" instead of an update.

1) Will I lose my bookmarks, settings, passwords, ect? (My bookmarks have been collecting for years....)

2) If I try this will creating a restore point return me back to the way I was before the attempt?

Thank You All!

My Firefox browser is somehow corrupted with foreign language features. See in the picture that much of the text is in English - the selected and preferred language. It is what the Settings are set to. But notice that bits and pieces are in some other language. I recently made a trip to Spain and used translation features while there - but those was all reset to English. I've gone into Troubleshooting mode; I've restarted; I've reset and restarted. But I can't seem to get rid of the gibberish. WTH!!!! All copies of Firefox, on all owned Mac machines (i-Phone; Mac Mini; I-Mac Pro; I pads) are set to English. About the only thing I haven't done it uninstall and reinstall Firefox. Thanks for any help you can offer.
