Ok, how is that account different from the others? I tried switching my google account but it didn't have a problem. Try changing the language or changing the theme, no problem.
I don't know what the cause is, I can't fix it. If you know the cause then please reply me.

I've checked both Windows and Mac in the latest version (v110.0.1), but it doesn't have a problem when pressing the zoom button and the menu doesn't pop up.

Please remove this add-on and install it in the latest version (Upload Today v5.4.7)
*** Not update. Remove it > Close Firefox > Reopen Firefox and install the add-on ***

I don't know what caused it. But I reworked the code sequence of the zoom function. Hope it solves your problem. If the menu still doesn't pop up Try using shortcuts instead.

HI. i have checked. It still works normally.

Can you try disabling all addons to just this one? If it works, it means some of your addons are in conflict with this one.

If it works then please reply me. I want to know which addon it is so I can check and fix it.

If not, what version of firefox are you using?
Previously, there were people who had problems with this zoom function as well because they were using Firefox Nightly, some versions that had problems.
