Firefox Support Forum

After a long time, I've decided to reinstall Firefox on my PC. Upon installing it, I got the error "Your firefox profile cannot be loaded. it may be missing or inaccessible." I cannot start Firefox.

After looking online, I found this article on the support page: https://support.mozilla.org/en-US/kb/how-run-firefox-when-profile-missing-inaccessible

I tried opening the profile manager, but can't get to it since Firefox won't start. It also is not accessible through using "firefox.exe -P" in the run dialog box.

So then I followed the directions and found my existing profiles.ini which pointed to my profile file. Wondering if it got corrupted, I changed the file extension to profiles.iniold and moved the whole mozilla folder to my desktop. Firefox continued to give me the same error message.

Finally I uninstalled firefox, deleted the mozilla folder under %appdata%, deleted the Mozilla folder under %programdata%, and deleted any mention of Mozilla in regedit. I finally reinstalled a fresh copy of firefox... and I got the same profile cannot be loaded error.

Is there somewhere that I'm not seeing that needs to be deleted to finally get a fresh install? I don't care about the original profile and am happy to start from scratch, but have no idea what I can still do in order to get to that point. Any suggestions on what I can do to completely remove any remnants of the original install from years ago?

Having checked with the Financial Times technical support, it seems that Firefox is blocking hyperlinks on my FT digital pages. This is something that started only a few months ago. Is there a setting in Firefox that I can use to cancel this unblocking; or do I need to do something else? The FT technical support suggest I switch to Chrome as a browser. I would rather stick with Firefox, but this problem is particularly irritating. Best regards, Ian

I updated the windows 10 installation on my Toshiba satellite laptop yesterday, 07-31-2022 and when i opened Firefox after that, it was huge - I have to dial it down to about 70% on the zoom to have it display even somewhat normally. I don't find any current answers when I google the question, so I'm asking here as I don't know what else to try. I've attached a screenshot to show how large it is, even at 67% zoom.

thanks!

Is there a setting where I can be notified before you take it upon yourselves to download/install an update? While I was away from my computer this afternoon I was hit by a Firefox upgrade that shut down my email and all my tabs. I've lost stuff I may never find again. If the MF'er responsible were in reach I'd punch his lights out. Seriously.

I am able open yahoo mail in my firefox browser, but none of the buttons are working. i cannot select a message by clicking the checkbox to the left of the message that is displayed in my inbox. if i select the message by clicking on the message, instead of being able to view it in the pane below my list of inbox messages, it appears in a new window. in that new window, no buttons are working. cannot delete, forward, reply, or use the back button to get back to my inbox. also unable to click on the calendar icon and see my calendar or click on the contacts icon to see my contacts. yahoo mail works fine in both edge and chrome browsers only having this problem in firefox.

When using the built in history side bar or history manager, after scrolling down and clicking on a link, it automatically scrolls back to the top. THIS IS SOOO ANNOYYYINGG!! Please tell me how I can stop this behavior so I don't have to manually scroll back down to where I was EVERY TIME I CLICK A LINK FROM THE HISTORY.

I need to scan a document and attach it to an email. It has been years since I did this and don't remember how to do it now. Need help to scan on my printer so that I can attach from my scans file.

This computer is about to crash so I have a laptop backup. I have copied my Firefox profile before from my last computer to this one that is crashing without issues at all. It copied all of my bookmark data, settings, logins, themes, add-ons, etc last time. This time it refuses to read any of the files copied. No add-ons, no bookmarks no nothing. I need this taken care of ASAP as this comptuer is on it's way down and the monitor likely only has days left the way it's running. Why does copying profiles no longer work? I know how to do it and I did the exactly the same as I did before. It's been an hour fighting with it and nothing is working. I need this done ASAP.

Since Firefox's most recent update yesterday morning I have not been able to access any of my Adobe Apps. I have checked that everything is update date, restarted my laptop, cleared cache history etc. Been in touch with IT and my colleague that uses the same account. It's not an Adobe account issue, it's definitely related to the firefox update on my laptop as that's when I stopped being able to use the Apps. Any ideas?

Firefox has a frustrating habit of closing windows and not restoring them properly. I had 2 windows with a multiple tabs open in each and Firefox will successfully reopen both windows until it doesn't. I tried all the methods with going into history or using the previous.json file in sessionrestore-backups but that file only had 1 window. Now I'm trying to use my browser history to see which websites I visited but all that shows up are the closed tabs - not the windows or the websites I was on before the tab was closed.

Where can I find full browsing information to restore my lost tabs? Alternatively I heard before Firefox updates it creates a snapshot of tabs/windows. How can I access this as a backup?

I dislike Chrome, but it honestly is much better at saving previous sessions.

Somehow all my add-ons were disabled. Was I hacked? I enabled Metamask but it won't open so that I can sign in to it. When I went to add-ons, Metamask was set to run in Private windows. I changed that before I enabled it. Why would I want to run an add-on in a private window, especially a crypto wallet? How can I open Metamask?

I want to test a group of sites to see if they accept TLS 1.0 connections.

Many sources including https://support.mozilla.org/en-US/questions/1101896 say that you can force Firefox to send TLS 1.0 requests by setting security.tls.version.max to 1, and I have done this successfully in the past to test if a site supported TLS 1.0. (Sometimes a site allows access over TLS 1.0 but disables certain features such as submitting credit card numbers.)

However, I am now getting inconsistent results when trying to do this. I set security.tls.version.max to 1 and restart the browser. Then I go to https://www.google.com/, click the padlock and navigate to more information, and it says "Connected encrypted (TLS_AES_128_GCM_SHA256, 128 bit keys, TLS 1.3)". Note, TLS 1.3. But I could swear the first time I loaded https://www.google.com/ the same dialog box said the connection was using TLS 1.0.

Meanwhile other sites like https://wikipedia.org/ and https://twitter.com/ fail to load with SSL_ERROR_PROTOCOL_VERSION_ALERT. I understand why (they don't support TLS 1.0), but I don't understand why the connection to Google is showing TLS 1.3 in the same browser window.

Is there some mechanism by which a site that initially accepts the TLS 1.0 connection, is then forcing Firefox to switch to 1.3, overriding the security.tls.version.max setting? That doesn't make sense but it's the only thing that seems consistent with observation.

Thanks!

I need to exempt a site from the pop up blocker process. When I go to Privacy & Settings/Manage Exceptions, there is no text box or other way for me to enter the site. Am I doing something wrong or do I need to change some other setting to allow exceptions?

Hi, so yesterday, I updated to the latest version of FireFox (version 105.0). Nothing seemed to be out of the ordinary until I decided to watch a few YouTube videos. The best way I can describe this problem is that every time I decide to scroll down to see the description or read a few comments, the entire screen on my laptop goes black regardless if it's on default view or full screen.

Even though that does sound like a crash, the audio still plays, and if I power the computer to sleep mode and log back in, the window of the video automatically scrolls up and everything is back to the way it was (but I did had to restart the laptop once because it also visually broke my mouse pointer). The only way I can get around this problem is to pause whatever video I watch and then scroll down, and no black screen occurs.

I don't know if I'm the only one who has this problem, but I've never had this issue happen in past versions of FireFox. If there is another way to fix this problem, I'll be glad to take anyone's possible suggestions/solutions.
