Firefox Community Forum

Hi,

I have a very old version of Firefox (51.0.1 64-bit) on Windows 7 Pro. I know it's well out-of-date. It's not my "main" browser, but there are some things I use it for because there are (were) some handy old extension on it. For example there's an extension that simply copies any text I highlight, without my having to press CTRL-C. I find the "scrapbook" invaluable for saving info offline.

Yesterday everything was fine. Today ALL the extensions have been disable because "[extension] could not be verified for use in firefox and has been disabled". There is no option to enable them again.

I have backups of the extensions (xpi files), but firefox is telling me that they appear to be corrupted.

Is there any way to either enable the disabled extensions, or force firefox to reinstall then from my backups? I have toggled "xpinstall.signatures.required" to "false".

Thanks for any help.

How do I stop Firefox from opening Finder in a new window? I don't want to have to go back and forth between windows. The same thing happens when I open a PDF. Thanks.

Last week my (very old) computer crashed and upon restart, Firefox was displaying the attached error image. I uninstalled and reinstalled Firefox several times in an attempt to get it to work but upon re-installation(s) every tab would just say "Your tab crashed". I was receiving the 'Bad Image' error code for Firefox as well as other software such as my pdf reader and iTunes. I took my computer to my local shop where they told me my computer was running out of memory and so they've installed some more as well as upgrading my 8gb RAM to 16gb.

I'm now able to run Firefox again, and my other software, but I've since lost the profile, with my tabs/bookmarks/history all gone. I'm super ADHD and so was very reliant on my bookmarks and my many tabs to organise my life.

I've tried importing old profiles from an 'Old Firefox Data' folder but none of them have my old bookmarks etc. The 'Old Firefox Data' folder seems to be dated after the crash.

I also did not have a Mozilla account at the time of crash. Is it possible for me to recover any of my old profile data? Any help would be greatly appreciated!

The Firefox 'Downloads, Save Files To.." location appears to be disconnected from reality. If I indicate either of the Documents or Desktop folders as the preferred save location, both of those folders present as being empty when in fact they both have numerous files/directories. Even if I try to save in "+ Other Locations", those locations are limited to the same as presented in the 'Browse' window of Home, Desktop, Documents and Downloads. Only the Downloads folder displays correctly.

Also as a result of this limited save location, I can only retrieve a file from the Downloads folder (the attached file was saved in my Documents folder but I had to move it to Downloads.

Why does the saving behavior behave like this?

Dear,

I use a hotkey for the screen-capture program "Snagit". The hotkey is: CTRL-SHFT-P

However, it now seems that also the AI-search program "Perlexity" uses the same hotkey.

Where can I remove the shortkey for Perplexity?

I have been using the iCloud Passwords extension successfully with MS Edge, but decided to switch back to Firefox as my default browser.

Having requested and installed the extension (v1.3.77.1), it shows as working in Firefox extensions management, and the icon appears in the toolbar, but a message is displayed when the icon is clicked, "Download iCloud for Windows to use iCloud Passwords".

The issue is that I already have iCloud for Windows installed and working, and iCloud Passwords working with Edge. It appears that Firefox cannot detect that iCloud for Windows is installed and working.

Please can you tell me if this can be resolved, and if so, how? Thank you.

Thought only Ubuntu's Linux Firefox 136.0 was 'unstable' on my Gateway E-475M laptop - crashes, restores session then freezes only to log me out, then completely locking up requiring holding down power button and rebooting...

Now, even Firefox 136.0 on WIN7 is crashing, then restores session only to go to the 'blue screen of death' requiring holding down the power button and rebooting...

Evidently, the problem is not with Ubuntu or WIN7, but either: Firefox (Linux or win version); or, the Gateway E-475M laptop (2.0GHz CPU, 4Gb RAM, 8Gb swapfile, Harddrive at 61% usage, Linux/Win on separate booting partitions, LAN + usb & pci wifi's, etc.) - both OS's used to work fine, but as upgrades to Firefox have come along, they have steadily gotten more and more unstable...

Sometime, I'm only making a bookmark, and it starts this circus act... does it on differing websites, etc. Firefox is the only thing loaded - using two windows on two different monitors ...at a loss as to what to do - Firefox is supposed to be THE lightest-weight browser out there, and was for awhile... the only extension used on both systems is "NoScript" - could that be causing the disturbance in the force?!?

Please assist or advise why Firefox seems to be slowing down my system by memory usage. I have a handful (6) of tabs open on 1 browser session and my system started slowing down so I checked my task manager and it shows that I have more than a dozen of Firefox instances open chewing up almost 90% of my memory.

Please assist or advise me on how to tweak my browser to perform better, and not to show ghost instances
