Firefox gemenskapsforum

On Thursday 3rd September 2026 Firefox stopped working. I tried lots of things to get it to work to no avail. Today, 8th September 2026, I had already deleted the Firefox that was already on my PC so I downloaded a fresh copy from the Firefox website and installed it. It ran perfectly for about 30 minutes then I shut it down. 5 Minutes later, a Firefox crash report appeared which I duly sent of. Checking Event Manager a string of error messages saying the same thing, Its the XUL.DLL file that keep crashing! This was the same file that caused the failure last week. I had made sure that XUL.DLL was not on the pc when I downloaded Firefox today. When I click on the Firefox icon it open but stays on a black lower half of the screen and boxes at the top, white lined but black and transparent lines moving left to right across them, eventually it fails and closes, after a few minutes it send the crash report. Its a shame because I have used Firefox for many, many years and now having to use Edge!!!!

I've searched & waited past few years for an Extension to make the TOOLBAR FONTS larger, none found. Reason being many of us are using larger monitors and TV's and we're usually sitting or standing further away from the screen. Problem is the font size cannot be changed, they stay small and hard to read comfortably. __YES I've reset my operating systems font size, that does not work in Firefox TOOLBARS. __Changing the "firefox/addon/theme-font-size-changer" has been eliminated by Firefox. __Changing the "layout.css.devPixelsPerPx" to a larger number increases the whole TOOLBAR. I just want the FONT size larger. __(someone suggested) NO, I'm not going to setup 2 monitors.

Sure would like this issue fixed. In the pix below, it has been done.

When I save the bookmarks to the toolbar they work fine but when I close and reopen firefox they bookmarks don't work. They are there but inactive and do not work. How do I save bookmarks so they open everytime I open firefox?

In the Settings, the "HTTPS-Only" feature seems broken. There is an option to 'Don't enable" this feature, but that doesn't make any difference. I can get to an "http:" site using any other browser, but not with the latest Firefox.

Hi!

I appreciate all the work put into developing 155, and I can't keep up. I'd like to get my book marks back. How can I return to an earlier version, unless you know a way I can get them in 155, Thank you! BTW I'm using Windows 10.

latest update seems to have broken firefox 155.0.1. It opens but then becomes unresponsive. Two different PC, both win 10. How can I revert to previous?

I can not get extra info from troubleshooting page cause FF won't open so as to be used.

Since 09sep2026, the "Currently" news area layout no longer displays text next to each photo. Instead there are vertical boxes with photos, then a short column with a few games, etc. boxes, then the right half of the page is blank. I have AT&T fiber internet service, which pushes "Currently". I have not changed any settings. I am still on Win 10, with an HP display. I have done all available updates to Win 10. Thank you for your assistance!

Какое то время назад, я уже писал, что перестал работать VPN в браузере Mozilla. После этого, через короткое время, VPN включили! Сейчас, снова, VPN перестал подключаться и работать. Когда же будет стабильность, в работе этого VPN? Включите, пожалуйста!

I want University Of The People student app restored on my new Mozila Firefox with Yahoo mail.com. I am a student and may drop out if I loose the contents I am asking for.

Your VPN has not been working in Russia for 5 days now. Just to write this, I have to wait about a minute on every page. Why does your browser work so slowly in the support section? The same site opens much faster in Chrome.
