Please help. I have no idea what to do! Do I delete Firefox and download it again?

Kind regards

Since the last update, my mouse is sticking for a second, from time to time. Whatever you did in that last update, I'm unable to use firefox. I have had to switch to google chrome until you fix whatever it is you broke.

When I run the Divi Builder on the agencia221b.com site, it crashes firefox.

The testes I've made so far: If i run divi builder from other sites in the same hosting, it crashes firefox. If i run divi builder from those sites in incognito mode, everything runs normally. If i run divi builder from those sites in firefox troubleshooting mode, it crashes firefox. If i run divi builder from those sites with all extensions disabled, it crashes firefox. If i run divi builder from other sites in other hosting, all runs normally. If i run divi builder from those sites in chrome, in or out of incognito mode, everything runs normally.

This problem started some weeks ago with one site, after instaling a wordpress plugin. Now, other sites in the same hosting begin to have the same problem.

It only happens with firefox, always. It doenst happens with other browsers, never.

Please, can someone help?

When I go to my site www.unitedcomputerconsultants.com the navigation menu loads, but the text links do not appear for 60 seconds. Although they seem to be OK in Windows machines. I am using an Apple Mac Pro Can you please help

After the latest update, trying to log into some sites, eg, https://web.emporiaenergy.com/#/login, the password field drops characters, takes 2 or 3 keystrokes to get a char to enter. Autofill fails miserably. What changed? This is unusable. BTW, tried with Chrome, no problem at all.

Several login pages don't load correctly, completely or at all since the last update. Binance homepage doesn't load the login menu (see attachment), direct url page just shows white screen. I also had some issues with logins on my health insurance site, downloading pdf's, everything just being incredibly slow, pages getting stuck, no loading icons. I cleared my cache and cookies, and it seems the problems got worse. I'm running a VPN, turning it off didn't fix these problems. Everything works fine in Brave. I tried troubleshooting mode, but once that was started up I didn't know what to do.

I've been lead to believe in previous editions of firefox you could turn off the redirect message and instead just allow firefox to redirect.

However now (as of 112.0.1) i can't find any way to do this. I repeatedly get redirect message and i would prefer the browser just do the redirect instead of having my click a link. I know exactly where the redirect is coming from and i have no problem with it and i don't need it to have a warning.

I know you cant help with part of it. When i launch a video i have bought on steam it now opens it on my default browser which is firefox, but it tells me its not up to date so i cant watch anything. at this point its forcing me to go back to chrome since it works.

Wh.en I opene my bank account website, I get the following message: "This page is slowing down Firefox. To speed up your browser, stop this page." It is followed by a box with the word "Stop" in it. if I click on that, the page freezes. Can someone tell me why this is happening and what I have to do to fix it?

in the last day firefox has all but stopped working on most websites. i can go to them and they start to load, but then they eventually break halfway through and either end up loading forever or produce an error. if i look at the console i see "Source map error: Error: NetworkError when attempting to fetch resource." this happens on twitter.com and raidbots.com to name two off the top of my head.

i did a complete refresh and even completely uninstalled and reinstalled the browser - it started working for a bit and then broke again. i have no plugins or extensions enabled currently (i have dashlane but this happens with it enabled or disabled). it's making the browser unusable. ive scanned my computer for malware and cant find anything either. i don't have this problem in any other browsers so not sure what else to try.

Hey people!

Stuck with an issue. Need your help. Tried all the documented troubleshoot options - like refreshing, disabling hardware acceleration, Recommended Performance, troubleshoot mode, etc.

New installation. Worked fine. Logged into Firefox Account for Sync. Since then, High CPU usage even with no tabs open. No clue why.

This is the profiler report: https://share.firefox.dev/3Khzq1C

Still stuck on 35%-50%-60% CPU usage with just one tab. And just a new blank tab!

The profiler report, if can be decoded in laymen terms, as to what activity is causing so much CPU usage, will be of immense help.

I have been using Firefox for about a decade. Lately, most of the websites I use have not been working properly (from utilies and providers to my own website admin page) Some adresses won't even start to load when enetered into the bar.

I have a lot of bookmarks and bookmarks folders, yes. But I hope this is not the issue, as I need them for work.

I am using Mullvad vpn. (found Mozilla's VPN pretty much useless : it tells you right away you're connected, even when it is not actually using proper tunnels yet, especially on IOS. and when locating the VPN in France, France's news websites would refuse to play videos, stating that I am in the US...)

I use Evernote a lot, but over the last few days it's clipper stopped working as well (when clicking the email link to verify my Evernote account, the link opening in Firefox never opens a page..)

I have to use Safari for half of my work online now, which means I will switch everything to Safari next week if I cant find a solution to make Firefox work.

I already erased and re-downloaded Firefox quite a few times. Changing, then resetting all preferences and security settings. To no avail.

Thank you for your help ! Loic

Is there something to Windows 10 and its DOWNLOADS folder that could cause memory issues? Firefox will only let me download so much to the downloads folder before it freezes up while trying to start a download. I then have to force shut down Firefox and move all the downloads to a folder to be able to start downloading again. Would it help if i picked a different folder to download stuff to? Why does this happen?

With the latest version 112.0.2 NordPass stopped functioning properly. Will not autofill. This happens on all 3 of my computers 2 are windows 10 and a win 7). Other browsers (Edge. Brave etc) work fine. I have cloned backup of system disks. I booted from a backup drive, which has previous version of the browser. and NordPass works fine. I tried several troubleshooting steps: turned off all other extensions - complete uninstall of NordPass and did an install - lowered security protection - used CCleaner & Privazer to clean system after each step. Any help would be greatly appreciated. Firefox is is my default browser.
