Since some time, Firefox (currently 89.0) on Windows 10 automatically reduces the window size from "fullscreen" to "maximized" when re-opening it from another program. So I have to wait until the window size reduction is complete before having to re-enlarge it again (which is quite annoying)
After a short web search, it turned out that this window size reduction is caused by the "xulstore.json" file in the profile folder and several other users are also reporting this issue. However, none of them in the forums I visited knew a permanent solution. I unsuccessfully tried the following:
- When I delete "xulstore.json", the window size reduction problem goes away only to re-appear after a few re-openings of Firefox (as the xulstore file is re-established then).
- Editing the xulstore file did not work, as Firefox overwrites it.
- Denying Firefox writing permission (via Windows) also doesn't work, as Firefox creates a temporary copy of the xulstore file which again causes the resizing problem.
- Denying access to this temporary copy does not work either.
It seems like Firefox does everything possible just to keep the resizing problem persisting. Is there any permanent solution (different from the failed solution attempts above)? Or even better: could you remove the automatic resizing in a coming version update of Firefox? It seems like I am not the only one who would be grateful about this.
