Diễn đàn hỗ trợ Firefox

Dear Support Team,

I am writing to request assistance with an issue I encountered after a recent Firefox update. After opening the browser, an automatic updat led to making all of my bookmarks, saved passwords and website data disappear. The profile I was using had been active for over two years and contained important information that I now cannot access (it wasn't a profile I created myself, I just used the browser normally).

I have already tried several troubleshooting steps, including restoring previous profiles, checking the profile folder, and attempting to recover data from backups. Unfortunately, none of these attempts have been successful so far. The about:profiles website tells me my old profile does not exist but in my Firefox folder, there is a (profile?) folder from 2023 which contains only one file.

Could you please help me recover my previous Firefox profile or guide me through any additional methods that might allow me to restore my lost data?

Thank you very much in advance for your support.

Kind regards, Sophia

Last night my machine updated itself but now I cannot access Facebook as it says I am using a browser version not supported by FB. I checked and my Firefox browser is indeed up to date. Have I been hacked or what?! Thanks. Geoff

My bookmarks in Chrome do not import into Firefox. I've Tried importing right from the Chrome browser and importing with an HTML file. No success with my bookmarks. I was able to import an extension, but I deleted it as that isn't my focus. I've checked the HTML file and it does have content (viewed in NotePad). I've looked in all the Bookmark options, but nothing imported there. I paused my NordVPN, no change. I've rebooted my desktop nothing changed. I'm running the latest updated version of Win 11.

Please advise.

My browser stopped loading certain pages, like Instagram, Facebook, and Amazon. Caches are cleared, extensions are disabled, tried service mode. Other browsers seem to have no problem loading these sites. What can be the problem?

I read the FAQ about this feature. I read this about whether the stories are personalized to me:

... When personalization does occur, recommendations rely on a process of story sorting and filtering that happens locally in your personal copy of Firefox.

But there is no place that tells me how to turn this off if I don't want the stories personalized to me, and I do not want them personalized. The algorithms make assumptions about what I want to read and learn. But I want to be free to encounter and learn things that I might not otherwise come across.

How can I avoid being pigeonholed and limited in this way?

I keep getting sporadic crashes, and sometimes a tab crash (particularly on maps.google.com). I have the latest updates to all my software. What can I do to help prevent these crashes?
