I've been using firefox as my default browser since it started, but yesterday it started getting weird. I open the browser and rather than open to the size of my monitor it opened to 1/4 size, next time I opened the browser it opened normally, next time 1/4 size and so on. I've looked at settings and it looks ok (not that I've changed anything recently) When it opens 1/4 size I click the top right to open full size and the 1/4 size browser moves from te left side to the right, the I click the top right full screen and it opens full screen with tools. Really weird! Has there been a screwy update?

Wubrane rozrisanje

Start Firefox using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh).


Do this several times in a row (open/close/open/close). Is the problem still there?

Thanks Fred, but neither suggestions fixed the issue. Deleting Windows: %AppData%\Mozilla\Firefox\Profiles stopped firefox opening, so I opened the recycle bin and restored the files.

I tried the safe mode as suggested, but that didn't fix it. In the end I "refreshed" Firefox and that did the trick. I think I did click the troubleshoot mode to get to it? Thanks for the Help Fred, you steered me in the right direction.

My instructions were to delete the xulstore.json file. Not the folder.
