Tabs overlapping/freezing

Hi.

Are you possibly using code in userChrome.css in the chrome folder in the profile folder that is no longer working properly ?

See:

• https://www.userchrome.org/what-is-userchrome-css.html
• https://www.userchrome.org/how-create-userchrome-css.html

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.

• switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
• do NOT click the "Refresh Firefox" button on the Safe Mode start window

I'm not using userChrome.css. I just disabled hard acceleration and switched to the default theme. I'll see what happens after a few sessions.

Hi Cor-el,

Unfortunately It didn't solve the issue. See attachment.

Hello, I don't know if this is the exact problem that you're having, but I found this solution to a similar problem: https://support.mozilla.org/en-US/questions/1052411

Are you using the most updated version of Firefox? Outdated versions of software contribute to the accumulation of bugs during use.

I hope that this helps.
