Φόρουμ υποστήριξης - Firefox

Hello. I've followed a bunch of suggestions from this Forum and elsewhere, but nothing seems to work. My main Firefox menu is stuck in Japanese as are the context menus and pop ups. Others are in English. I've uninstalled Firefox and reinstalled with English version. All settings (about:config, etc) are set to English, don't have Japanese included as additional language or anywhere else. Help please, it's driving me crazy...

The advice managing add-ons is to go to about:addons and choose the addon to remove. But the US language addon is not listed. Whenever I install the UK language addon, it is removed and replaced by the US one at the next "improvement" of Firefox.

How can I set the options so the US language and dictionary are never again downloaded, installed, then made the default environment?

After AVAST found an error in firefox and tried to fix it, firefox will not open unless it's showing as the attached image I have uninstalled both programmes, reinstalled firefox, restarted my computer several times as well as tried a system restore point but to no avail. Any help is very appreciated, I need it running soon to get my assessment pieces done.

Hi Guys,

(I'm not too well versed with the intricacies of how Firefox works under the hood, so please bear with).

Yesterday, on opening Firefox, Avast (virus protection software) browser cleanup tool stated that the Language resource pack (this was yesterday, so I'm not sure if that's quite the correct term) was disreputable (2/5 stars). Avast said I should remove it, so I did (yes, I probably should've checked, but I was in a hurry).

Firefox was running perfectly fine before, but now only boots as an unresponsive white panel with <window id="main-window" ^ in red text in a red bordered box at the top. (I would attach an image, but the uploader doesn't seem to want to play ball). </p>

Avast states on their website that removing an addon deletes it and the process cannot be undone.

I have tried uninstalling and reinstalling Firefox multiple times (with restarts) with no change, even with the 'remove addons and reset to default' checked.

I can't give you troubleshooting information because Firefox remains an unresponsive white panel - no addons, no toolbars to select 'help' from.

Any ideas? Please let me know if there's any other information you need to help fix this problem, I'd really like my favourite browser back!

my laptop did an update on something and when trying to start firefox I now just get a yellowish nearly full page box with the following text in a section at the top "<window id="main-window" ^ ". Uninstall and new install does not change anything. </p>
