Is anyone looking into this? I found an article that told me to remove some cash files and it seemed to fix the issue but it continues to reoccur. Some apps such as MS360 Outlook seem to trigger it, but if it was truly just a corrupt cache issue then cleaning the cash/profile once should have fixed the issue. Instead its become a constant pain in the *** and I'm tempted to find another browser. Seems very recent as well as I've never had issues with firefox before.

Been using Firefox for over a decade. But lately is has become so slow now. Often freezes up if more than two tabs are open or a website is in any way very complex. What settings and issues should I check? What has changed? I can run the same sites on Brave and Edge browsers with no issues or not nearly as slow and bogged down.

Hi whenever I use my Google account to sign into websites (Google, ebay, YouTube, & anyother sites,) Firefox will become unresponsive, the window containing the tab i was using becomes unresponsive, sort of. - I can't click any open Firefox Tabs, - the red 'Close' radio button is greyed-out, so I can't close any tabs or the window - right-click is unresponsive, so i can't close tabs that way, but Command-W closes the tabs normally, but the others are still unresponsive.

- i can open a new Firefox window (with &/or without Tabs,) which works normally.

- & unrelated, but earlier, Firefox was running really slowly, Youtube videos were slowed down, but audio was normal, and scrolling was slow.

My mouse (wheel) only works on the portion of the page that is currently visible; it will not scroll down the rest of the page. This problem began after 151.0.1 update just a few days ago. It works correctly in other applications such as word or excel. It also works correctly with other browsers, so it is definitely something in Firefox. Any ideas?

Hi, I’ve been experiencing slow startup times in Firefox, especially when I have my Time calculator web app open. The browser takes longer to load and sometimes becomes unresponsive.

I’ve tried disabling extensions and changing my home page, but the issue persists. Are there any specific settings or troubleshooting steps in Firefox that can help improve performance when using online calculators like this?

Any guidance or tips would be greatly appreciated. Thanks!
