Firefox Support Forum

I am busy doing my schoolwork and firefox keeps on crashing, namely by over-using the CPU on my laptop too much. I have tried numerous routes, such as reducing the number of browser extensions, using one of the certified performance-boosting add-ons to reduce CPU usage, I even tried limiting my tabs to a maximum of 10, all of them have failed to improve performance. This is not even mentioning the browser-induced bluescreen I just got a few minutes before writing this.

All of a sudden - Both of these websites below give me 403 errors. I cleared the CACHE, rebooted, checked the other settings - Nothing has been changed and I have the most recent FF version installed - 84.0.2 Also both of these can be accessed from any other browser - so it must be a FF issue.

I have used both sites for a long time with no access issues.

All help appreciated! JM

Hard to explain why I am asking here, but here goes:

I am a reseller and use different sources. One of our vendor's websites is showing me retail pricing after I login. Our special prices used to (and are supposed) be visible. If you don't log in, no prices are visible. My sales rep asked IT, who said to clear cache and cookies. And again today, he said it is on my end, not theirs.

Of course, that doesn't solve the problem. Do not even know where to begin.

Thank you.

I want to import my mobile Safari bookmarks into Firefox on my desktop. I have read many articles on here but none of them have helped. I had hopes for this one(https://support.mozilla.org/en-US/questions/1285031) but it was unclear whether the user was on a Mac or PC.

I have already installed iCloud for Windows and the iCloud Bookmarks add-on in Firefox. I have supposedly performed the sync operation already, but nothing seems to have transferred. I have neither the Safari bookmarks in Firefox, nor the Firefox bookmarks in Safari(which I do not want or care about as Safari will be deleted when I am done with all this) I don't see any options to adjust any kind of settings in either program.

I very much would like to get this iCloud thing to work. If that continues to be unsuccessful, is it possible to create an HTML file from the mobile Safari bookmarks and import THAT into Firefox?

Any help is greatly appreciated!

I have posed this question under "Fix slowness, crashing, error messages and other problems," and under "Other," and have not gotten a single response. So I am trying it again here.

This is a major glitch, and I am surprised that no one else is dealing with it too!

Is there anyone who works for Mozilla who monitors these forums who can help?

After upgrading to FF 84, my previous sessions are no longer saved and restored unless I restart in Safe Mode.

- I have Restore previous session checked in Preferences.

- I have opened new windows and tabs and one by one disabled and restored every add-on that I have had enabled and quit and restarted each time, until every single add-on has been disabled, and still the previous sessions are not saved and restored.

- I have looked in the sessionstore-backups folder with each restart, and there is never any file for the previous sessions in it.

- I have cleared all my cache before quitting and restarting.

- Again, even when there are absolutely no add-ons enabled, the previous session is not saved and not restored.

- Again, only when I restart in Safe Mode is the previous session saved and restored.

What is the solution?

Since, the update to 84.0.2(64 bit), my bookmarks toolbar has stopped showing the bookmarks that reside under the Bookmark Toolbar folder and it keeps on showing the message "For quick access, place your bookmarks h ere on the bookmarks toolbar.", even though I already have 10-12 bookmarks under bookmarks toolbar.

Firefox Sync sign in is stuck.

I've noticed for about 2 weeks now, my google street view is not working like it used to. It some times will not respond and when it does respond it is very slow. I didn't used to have this problem, so maybe a new Firefox update or some other issue is causing then problem? How can I view my browser settings to see if some thing there is causing the problem? Hopefully, someone can help and cure the problem. Thanks,

Hello! I love firefox, but latest versions have a feature that disturbs me a lot. I’m using more than one screen with different dimensions. Then I move firefox window from one screen to another, firefox automatically adjust his window size accordingly. Please, tell me, how I can disable that feature? Thank you!

Hello, on Firefox I want to activate browser.translation.bing.apiKeyOverride, on site https://portal.azure.com how I can receive browser.translation.bing.apiKeyOverride, can you help? Thank you.

P.S. From page https://wiki.mozilla.org/QA/Translation I use J5dY1fzkZwQP2Mq56ssXFF/G0dwrscNmCjSgaxl0CNE= and TestFirefox and I receive error.

On my old computer - Linux Mint 19 with current Firefox installed, I had enabled an account and set a master password. Now I'm upgrading to a new computer. Firefox does not recognize the old master password. I found the setting to enable a new account password, but through the multiple jumps needed to get this set up, it frequently locks me out for 15 minutes. You encouraged saving passwords in Firefox. Switching the method for storing the passwords between versions and then having frequent 15 minute lockouts will make me abandon this platform. I don't have time for this. I do have my passwords backed up, but there is no where in Firefox that I can see in the passwords section to import from Firefox. I'm very disappointed.

Hallo, since I've switched from InternetExplorer to FireFox as the standard browser, I cannot open MHT-files which I downloaded from the web. Firefox starts to open new tabs, by the second, endlessly. The process can be stopped only by killing Firefox with the TaskManager, several times. Is this a bug or a feature? Many thanks Ante

Hi, The vams.cdc.gov portal is just showing a blank page, the cdc site says that firefox is a browser to use and also says chrome,safari etc. I need to get on the site because I have to register my mother for over 75 to get the vaccine. I have a phone modem and windows 7. Trying to download either of the other browsers is a long long long download. Anybody know the fix to getting this portal working. I noticed that it uses the Aura framework ie window.Aura By the way the page source is there, and the title bar does show VAMS Portal, just the blank page though. Thanks for helping if you can.

I sometimes copy and paste things from websites onto word documents. I like to keep the same style font/spacing/etc. when I do. When I use Chrome or Explorer or Edge the font and spacing stays the way it looks on the webpage, when I use Firefox it changes to the default (Times New Roman, double spaced, etc.). If I use "Merge Fonts" it only pastes to what the last thing I typed looked like (not what I want), and if I start a new document and paste something there, it's back to the default settings. Is there anyway to get this working the way I want it, or am I going to have to go back to a different browser for this particular issue?

My logins and passwords keep getting removed. I have to go and place a copy of the key4, logins, and logins.json back into the folder. Every few days the logins and passwords shows no synced logins found.

Hi,

My Firefox sync data for a specific addon is messed up. I believe the temporary containers addon made Multi Account Containers addon to sync an insane amount of containers, maxing up the sync storage. Now whenever I click to sync MAC, it downloads thousands of 'tmp' containers. It refuses to sync ever again, hence no matter how many times I fix it locally, if it ever syncs again, it downloads the thousands 'tmp' containers again. How can I delete the sync data for good?
