Diễn đàn hỗ trợ Firefox

I am having an intermittent problem with bookmarks not loading when I open Firefox.

Is there a fix for this?

I have noticed that a lot of answers on here refer to features that no longer exist in settings.

Mini tanx,

I have had Firefox using autofill for credit card payments for years--just replace my iMac with a new Mac Mini, and the credit card info still pops up when I am making a payment, but it will not autofill.

Hi Mozilla I hav got a problem with Firefox on Kubuntu 24.04.3. Everytime the computer is restarted Firefox crashes the first time it's started. That's not a big problem, starting Firefox again don't take long. But the problems is exceeding. If i start Firefox by clicking a link in a mail in Thunderbird. And Firefox has not yet been started, It crashes, but now it's also invaliding the Task bar on the screen where Firefox was started. Invaliding means that I cannot start apps from that screens taskbar, and the clock has stalled, none of the tools works etc. The only possibility solution I have been able to figure out, is restart (It's like going back to Win 98). Sometimes I am able to start a app from that invalid taskbar. But it's not the one app that i clicked on. Even though I can trigger it via Thunderbird, the invaliding of the taskbar will occur after a while. And I have to restart. I am not sure if this is the right place to post. But Firefox is always involved, but maybe Thunderbird or Ubuntu was the right place? Every time Firefox crashes there is send a crash report to Mozilla, but is has been going on for a while, so i guess that nobody is looking at the crash report. If I use Chromium instead of Firefox I don't see the problem.

All of a sudden I can no longer add bookmarks to my Firefox desktop. At this point I can not even access the "Bookmark current tab." Are there settings that control the Bookmarks section. Thank you

Once again, when I updated Firefox, it changed a LOT of my settings, including displaying the toolbar and open tabs bar.

When this happened last - months ago - it seems Mozilla realized this had happened to a lot of users, and managed to restore us to all the information that had been "lost".

I hope you can do that again, and can find a way to not put at least ME, and I'd bet a lot of other users, through the OMG!!! What do I do NOW?! panic.

Happy Holidays.

Please help, can anyone answer me. I am on Windows 11. Asus laptop PC. On Google Chrome, any streaming website I used with autoplay enabled would KEEP full screen mode ON after changing episodes. It would automatically go to a new page with the following episode and remain full screen. Why doesn't Firefox have this feature?? I'm seriously considering going back to Google Chrome for this one small feature. Every time I had any streaming service playing with autoplay enabled, I didn't have to manually select the full screen option every time. I am having to stand up and manually click full screen function. Every. Single. Time. This needs to change PLEASE.

I am looking for confirmation that Mozilla is moving to an 'AI browser'.

Will there be an option to not use this data harvesting LLM garbage or will mozilla be abandoning their core values?

I read online that Firefox is planning on implementing AI features. Given the track record of AI in other browsers leaking private information, bogging down connectivity, and generally being a nuisance towards users, I was wondering if there will be opt out features in future updates? Or know of forum threads that will update with tutorials on how to turn off AI features?

If not, does anyone on this forum have recommendations for no-ai browsers?

Where sis my bookmarks go. I don't have time to screw around with hunting it down. It was here yesterday. Today it is gone. I've tried to restart, I've tried help, I've tried all the list of things but the bookmark on the header thingy has disappeared.

I have happily used Firefox for years now, but I avoid using AI for both privacy and environmental reasons. I am extremely concerned by Mozilla's increased emphasis on these technologies. I do not want, nor will I put up with, new AI features in my browser. If the company continues this push, I will move to a different browser. It'll be very annoying, and I'll be really upset about it, but it's what I'll have to do if y'all keep going down this path. Please stop.

This refurbished laptop was purchased from Best Buy in August 2022 with a Windows 10 OS. When a free upgrade was offered by Microsoft to Windows 11, it was accepted. Why are there no drivers with a version 11 prefix?

Seit dem 25.12.2025 habe ich meine Lesezeichen und Passwörter, wahrscheinlich nach einem Update oder einer unbeabsichtigten Fehleingabe nicht mehr zur Verfügung. ich möchte meine Firefox-Version wieder auf den Stand vom 24.12.2025 zurücksetzen. Was kann ich tun oder kann man auch telefonisch Kontakt aufnehmen in deutscher Sprache?

Saying "you can turn off the AI" is NOT enough, Mozilla. Nothing is ever "turned off" unless it's completely removed. This is Microsoft's playbook BS; "but you can turn it off", but for some reason the system is always using a metric ton of memory, lagging and whatnot. You, of all companies, should know this and be better than that. Nothing good is ever force-installed and impossible to remove. Unless you all make it installed completely separately so people like me, who are a significant part, if not most of your user base, can not install it, nothing short of a full renunciation of the CEO will suffice to make we trust you again.

"Internet for People, not profit" is seeming more and more like blatant false advertising every day.
