Firefox Community Forum

Firefox consumes almost 2Gb of RAM with only one tab open. I find this surprising, and it's a major performance issue for me.

Do you have an explanation or solutions to reduce this memory overconsumption?

Hello! After the recent update, any text I insert remains without spaces and all words are written together. I disabled all extensions: no result. The problem did not occur in other browsers.

Developer edition seems to be blocking Today's Deals when browsing amazon.com. Regular firefox does not do this. Suggestion on what to do to fix it.

Also trying to browse distrowatch give the following: Warning: Potential Security Risk Ahead.

I was working with responsive view mode and noticed that sensor scroll with mouse is broken. I checked on another PC and the problem there too. I don't know how to describe it, but I made a video and uploaded it to a website so you can watch it.

There's one specific field I fill in very often and for some reason Firefox is really keen on suggesting me two searches that I looked up more than a couple months ago, on a totally different site. I can't even remove these suggestions or add new ones. When I used Vivaldi, it'd learn what I insert (even if it'd end up suggesting tens and tens of options), while Firefox doesn't learn at all.

For sake of an example, let's say that the word I use every day in this field is XYZ. Not even once was it suggested to me, I've only ever gotten the two in the screenshot below instead. And I can't remove them using the Delete key as some other article suggested.

Speaking of which, I just noticed the same thing happen to the subject line in this form 🙃

Hi, I hope you are doing well.

I have been having issues since this morning. I am unable to open a new tab in the Firefox developer edition.

I have attached screenshots. I have tried to reset settings; I have tried to uninstall and then install again, but nothing works.

Firefox has "Open previous windows and tabs" ticked in Settings. I had to force restart MacOS, and upon starting Firefox again my existing windows are invisible. They are shown in the Window menu and when right-clicking the Firefox icon in the MacOS dock, however when I select one of the windows it does not become visible. Command+` does not show the windows either.

I can however open new windows.

I tried renaming xulstore.json per this old article with no effect.

How can I make the existing windows visible again?
