Diễn đàn hỗ trợ Firefox

I use Firefox on Linux Debian 11 (Bullseye). After a recent automatic update to Firefox 91.10.0esr, some websites will not load (just sit with a blank page, showing flicking loading symbol). Examples are ocado.com and abelandcole.co.uk. I have tried all the usual things to fix, including, switching off VPN, clearing cookies and caches, running in safe mode, all with no success. Both sites run fine in Vivaldi and Brave. I have eventually got the pages to load by disabling IPv6 in Firefox. Clearly there is a problem with 91.10.0esr. I'm not sure whether the workaround of disabling IPv6 might cause other problems or weaken security or privacy?

I turned on my computer like any other normal day this morning, except when I launched firefox it was like it was freshly installed, all my passwords, usernames, cookies, saved bookmarks, work related history material is all GONE it's like I just installed firefox for the first time. A lot of these passwords I dont know off the top of my head so I'm going to have to ask my business partners for ALL the passwords... Why did firefox do this? What is the problem??

I don't know but I'll say that I've tried using troubleshooting mode, cleared my startup cache, reset the browser and redownloaded the entire application. this happened after I cleared some stuff from my laptop don't know if that has anything to do with it though

Ok, there might exist a solution to this, but I am not able to find it or even a better way to explain it.

So, the main issue is, I have a lots of tabs open on my Firefox (Linux) and after some minutes of inactivity, Firefox automatically deletes all the data associated with that site.

So, when I switch back to that site, it reloads.

The main issue is with Whatsapp Web, as I don't get notification if I don't switch to the tab every now and then.

There might be a option for this behavior in the settings but I can't seem to find it.

Please help me find a solution.

Thanks

When I try to access MediaFire it doesn't load and get errors etc. And other sites are slow etc. Is there anything I can do to fix it? Also how do I contact FireFox email official support? I don't like asking on the forums since I want a legit agent ;p

Since upgrading to 100, I am unable to log in to Florida Unemployment site. I have followed all their recommendations and still am unable to access. Also, when I click on an item, new tab is opening in place of one I clicked on instead of new tab.

Follow the dialog at homelink.com to report an error with a garage door remote problem. Clicking on "Submit" gets a 404 error. I've had similar problems with other website dialogs, but usually the link is just ignored. For example rockler.com, when attempting to place an order - nothing happens. In both cases, switching to MS Edge works correctly.

When I go to www.tractorsupply.com, and click on "My Wallet," I get the error, "Prohibited characters error." The My Wallet is an area reserved for special offers that the shopper can load to the shopping cart.

Hi, I have this problem which I never faced before, and I could not find a solution to it online. Could you please help me! It only appears in your browser. Which is a pink layer on YouTube videos. I tried reinstalling the browser, refreshing it. everything I could. And no chance. I am going to share with you a screenshot of what I mean.

I cannot seem to narrow this down. I am getting a ntdll.dll exception within the error that I see in Event Viewer -> Application logs. This issue is reproducible on two different computers, opening various sites. I suspected it was extensions (as those would be a commonality) but I had the same crash occur in Troubleshoot Mode. It does happen less frequently on a newer machine, but it still happens. I find that opening something such as YouTube or The New York Times makes it crash faster, meaning some performance thing.

Attached are two distinct errors that happen each time.

Hi, when I visit some websites, the pages do not work properly. The page does not want to upload properly and links on the page do not work. Can't log in to a page I have the latest version installed.

The Firefox prefs.js file was quarantined by avast yesterday. Message indicated malware had infected the file. Now when I click on the Firefox icon the MSN browser comes up. How can I get back to using Firefox safely? Can I uninstall Firefox, then re-install it to make the problem go away?

Please help me remove this blank area section on the web pages. its on all of them on every tab. I have tried restarting and updating. I cant get it to go away.

thank you Mark

I seem to have gotten something called Google Ad Services. It frequently interferes with my getting to websites and I cannot find how to block it or remove it. HELP!
