Firefox Support Forum

I had Firefox opened in a main windows with maybe 50 tabs of tabs I wanted to look at (documentaries, stand-up shows, stuff from work etc). I opened a second window and while navigating in the second window I mistakenly close the main. As one does, I hit Open recently closed window. Guess what? Firefox opens a window from yesterday and a few more empty ones, but not the one I just closed. Can someone help me with this?

Is it possible to import my Opera bookmarks into Firefox? The only selections I've found in the Help file is from Microsoft Edge, Edge Legacy or Internet Explorer. Perhaps there might be a workaround?

When I try to access [https://www.surinenglish.com/] I got the following:

Forbidden. You don't have permission to access / on this server. Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request. It has worked fine on this system and this browser before and still works fine in Vivaldi. No changes in AV software and no improvement when all extensions disabled. What could be causing it in FF (latest stable, Win 10)?

I was gifted an Amazon Fire Tablet to use for an upcoming hospital/rehab stay. I use Firefox on my desktop and Android phone and want to use it on my tablet, but the Amazon store doesn't have the app. Not sure I trust the Amazon Silk browser, but I may have no choice. I am not a tech savvy person! I don't know the difference between a bit, byte, or buttercup. If there is a way to install and use Firefox on my tablet, and sync with other devices, I would like to do so. Please explain how to do it as though you are talking to a 6 year old (who probably knows more about this stuff than I do, anyway). Thanks. rennylloyd

For some strange reason Firefox is not logging me into my favorite websites automatically any more. I have to manually log in every time. The websites' login pages are automatically filled when I move the cursor to the Username and Password fields, but I still have to click Log In. As soon as I log out and log in I am asked to "Sign In" again. I tried manually adding a website to the "Saved Logins" but that did not help. Using Windows 10 64bit.

On my internal sites I'm getting this error SEC_ERROR_INADEQUATE_KEY_USAGE

My other colleagues using FF v82 do not get the error. I have cleared cache and cookies , but still not working. The browser is not even giving me an option to proceed. How can I get past this ?

Where is the Forum? This is a FAQ-Site, not a forum? Why do you make it extra hard to file a bug? Or to go on an actual forum/board? What community is supposed "to help"?

I am unable to access a website that I regularly use. There is a warning see below.

"Decryption failed because the HMAC could not be validated."

I have used another browser to this website and can access OK.

Any Ideas?

Hello everyone

After updating to firefox 82 I am having issues with rendering. After every few minutes the favicons, icons etc stop displaying correctly and someitmes even the content on the page is not displayed properly. Please find image attached. I either have to restart the browser or it starts working again automatically after around 1 minute.

Please suggest how to resolve this. Regards

When wanting to play a game it is said that the AdBlocker should be put off first. My steps are go to the main menu, add-ons and watch the list of my personal add-ons. I have no Adblocker in my settings in add-ons. Secondly there are many Ad Blockers and it is not said which one.

So where is this question coming from, from Mozilla itself? Anyway how do I make the Adblocker switched off then when there is no button shown at all? Might there be a failure in the provider of the game?

Hi,

I brought my computer to Best Buy for some audio issues it was having. They reset my OS and drivers and now I lost all of my Mozilla Firefox bookmarks and passwords. I do not have a recent JSON backup file. How can I recover these?

Thanks.

After latest Windows 10 update (2004 or I don't know firefox is telling me I have Windows_NT 10.0 19041 so who knows) about month ago and after that Firefox keeps randomly crashing into desktop. It happens about 6-7 times in a hour! 95% of the time even crash report doesn't show up so I can't send my crash report to firefox. I have updated Firefox, downgraded it, disabled all add-ons I have tried that "media.wmf.vp9.enabled" trick and it doesn't work

When I try to backup my Firefox profile to a remote hard drive using SyncBackFree, i get an error message that access to the logins.json file is denied. SyncBackFree is trying to overwrite the previously stored version with the current version. No other file in the Firefox profile is similarly affected. How do I fix this problem?

Hi! Let me get straight onto the point, images aren't loading on websites. It's shown in the image below. It just started happening and I didn't find any help while googling.

I hope I get some help with this, thank you.

Hi!

I don't really need this feature and I have issue with finding any solution. I would like to disable this. Can you tell me how to do this?

Thanks in advance!

Unwanted tabs (as many as 10 last time) keep opening when I'm on Facebook (and sometimes Amazon) even though I don't click on anything. It's driving me nuts. How do I stop it? Thanks.

Page loading in Firefox 82.0 is way too slow, including on your own site, mozilla.org. It was even worse till I got Norton Security Suite to fix their problem, but it is still way too slow. Please fix asap.
