How To Clean Out Prefs That Are Clearly Old And Out of Date?

I have used and updated Firefox for years. I am now on v79. And in my prefs.js file (about:config) there is tons of old crap. Things like references to old addons which cannot even be installed any more and were removed during updates, prtiner setup stuff for printers I no longer own, and something that is causing the rendering of chase.com to be messed up and the site unusable in FF.

Is there some reasonable way to clean up the prefs.js? Using about:config does not seem to remove entries, only reset them to default. If I exit FF and edit the file in my text editor, FF doesn't work right when re-started - I have to restore the profile folder from a backup.

There must be some way. Any help/tips?

Thanks

I am having problems while trying to watch YouTube with the Firefox browser. I keep getting as yellow bar at the top of the page when trying to do anything on YouTube. A screenshot of the error is attached. I've asked Mozilla about this before, and I am also trying to get a fix from Dashlane. It concerns the message "a script in the extension Dashlane is causing Firefox to slow down" then it shows Learn more. When I open that if the warning stays long enough to click on it. It recommends changing dom.max_script_run_time. It shows it is set at 10, and will not allow any change as suggested. Then it suggests adding JavaScript toggle on and off. That does not help either. I would thank anybody between Mozilla and Dashlane that can provide a reason for this continued error message and how to fix it. This has been going on for months.

Does MS Update (Edge) (KB45569309) Pour mollasses over FF ??

I have a brand spanking new system with Win 10 installed on SSD. I've been using it for about a month and it works great. MS updated edge over night (SURPRISE) and now Firefox has been slowed down considerably. For example. Facebook loads OK, but as I scroll down, the "Like", "Read More" , "Comment" links don't work for a bit. On this site trying to bring focus on this text area is laggy. Not like before update.

They seem to show up after a while, but it seems like every site is somehow s-lo-w-e-d since this 'update'. I re booted and also ran the 'quick fix" option but stuff is still slow.

Of course the update can NOT be rolled back. Do y'all imagine this is intentional or just my imagination?

Hi,

I'm getting bored with firefox...

Spent 2 hours trying to find on internet or compare the about:config of my laptop/desktop to try to see what the problem.


on desktop on some website: when i click on a link, lets say an ssd deal for instance, i cannot reach the page and a small notification appears on right bottom corner (not below bookmarks like a popup) saying : "redirection canceled" and bring me back to the original page. on laptop same version of firefox (and same general settings) but no such problem, i started to compare each value in about:config but i stoped before becoming crazier.

whatever option i disable (website tracking) its still there, if i open in new private tab, the same.

So bored of spending so much time on some stupid option it seem i cannot have control over it, as i'm sure its just a simple value i have to change somewhere but cant find the info.

So please, if i was clear enough it my description, tell wich command i should change to get rid of it. Alternatively: is there a way to copy the config from one firefox to another? (like this i might copy config from laptop to desktop.

thx in advance for your eventual help

When i try to look at an image on firefox in it's own tab so i can see it bigger, it instead opts to download it instead of just showing it in the tab itself. This is annoying as I don't want to have to make a whole folder just for images that i've seen once and then never look at again. is there an option i might have chosen at some point that enables this? i'm not too sure. please help if someone is able to.

All the thumbnails except for the starting page are blank when restarting the browser. I need to click on each and every tab to make the thumbnails show.

Is there a way to change this? It drives me up the wall, especially when having to restart multiple times -which happens a lot due to several factors. I have vision problems and need the thumbs to show to find my way around quickly.

Thanks.
