How to fix Firefox on Windows 10?

Question

Windows

For the umpteenth time, Firefox has broken. The mouse hangs. All tab clicking animation effects do not work, switching to another tab takes 10-20 seconds. Everything is revealed through eternity. At the same time, the memory does not eat too much.
Completely deleted 3 times Browser RenoUninstaller. Cleaned extensions, cache, history. Every week firefox died.
What could be the problem? (OS Window 10, medium laptop)

Answer 1

What could be the problem? (OS Window 10, medium laptop)

There is a defect in your genes.
You killed your own system.
All sorts of shit.
And then people like you krivorukov write that Win is buggy.
PS:
Firefox has been living with me on Win 10 since the release of Win 10.
Win 10 was not installed from scratch, but was updated from 8, and that was updated from 7
And even in such conditions, Firefox works perfectly.
And you are a krivoruk who installed shitty software like Renault Uninstaller into a normal system.

Answer 2

RenoUninstaller - a verdict on the system.
FF has nothing to do with it)

Answer 3

If it makes you feel better, my Chrome is dying...

Answer 4

RenoUninstaller, of course, has nothing to do with it.
Only crooked hands are needed to spoil something with them. Well, just unique.
The answer may lie in the sites you visit, because Firefox doesn't die right away. Plus, check it with AdwCleaner, just in case.
But more often the reason for such garbage is installed add-ons, which die gradually on new versions of Firefox. But the author, asking a question, not only didn’t name the add-ons - he didn’t even bother to name the version of the browser. Meanwhile, on the new 55.0.2, even such a common add-on as Custom Buttons can gradually cause the browser to freeze if it was installed with AMO, that is, unfixed.
Another thing is that no cleaners are needed to uninstall Firefox. The staff member is doing well. And the browser itself rarely requires reinstallation. Problems are 99% in the profile. You can clean the history, you can not clean it, if there are errors, they will remain. You need to try not to rearrange the browser, but to create a new profile (firefox.exe -p -no-remote) and try it on it. Bookmarks, passwords, history, and so on, just transfer from the old profile (read:) + do not forget to transfer favicons.sqlite if the version is>=55
