after working in firefox for a while and using a number of windows and the I close firefox with multiple windows open in my session. if i open it again and keep doing this for a while and then have closed firefox, eventually I can no longer open a firefox window and get a message the I have too many windows opn and can't open more till i close the open windows. i hover over the firefox app and all the previously closed windows are stacked up. why didn;t they close when i exited my firefox sessions. why are they still there and clogging up the system?

I have Firefox 152.3 (73911) on iPhone with the latest iOS 26.5.2 On Firefox, web pages not showing up when switched between open apps on iPhone.

I can see web pages on Safari.

Noticed that Firefox on IOS was updated about 17 hours ago, so that may explain the current issue. When I open the app on my phone, it will be on the page I was last on, but would be frozen. Cannot add a new tab. Cannot add an address to in address bar. Nothing can be done u til I force quit the app, and then reopen the app afterwards (as long as I give it a couple seconds afterwards). Didn’t have this issue the day before.

I love Firefox and have used it forever. But its memory usage is killing me lately and I'm seriously reconsidering.... PC, Win11, Intel7, 16GB memory. (I'm typing this from Chrome)

I've updated, restarted, but it keeps maxing out and slowing my computer to a crawl. Somebody please tell me there's a fix pending?

suse linux 15.6 firefox 140.9.0esr (64-bit)

An aggressive website can cause "isolated web co" processes to be started. When they hog all processors and memory, the computer besomes unresponsive. Keyboard and mouse freezes up.

Is there a way to limit firefox processes to n-1 processors, leaving 1 processor available for me to kill it ?

I go to a website and it tells me that it has emailed me a code. I have to go to another app to bring up my email to get the code. When I go back to Firefox using the recent apps feature, on my phone, Firefox reloads to the previous page and I have to start all over again because you've gotten rid of the page I was on, to put the code in. It's an endless cycle. Since I'm not actually closing Firefox why can't it open onto the page I was just on?

When I try to browse the webpage still not show anything or loading about 30-50 Second before start loading. Sometimes it get freeze not show anything need to re-enter url.

i am using honor magicpad2 today there is non sync with my keyboard and mozilla.looking for update but none .my keyboard was working well but not i cant see what i wrote .everything comes later.thanks.

Latest version(s) of Firefox on my Android 16 Samsung Galaxy 25 Ultra are not happy - go to open a new tab and the entire app freezes - after about 10s I get offered the option of waiting - which does nothing, the same message reappears again 10s later - or closing the app.

Have been trying to find resolution as Firefox is my browser of choice but nothing so far besides reverting to an old build of around 140 and refusing to upgrade.

Please can this be looked at as a priority - reading up I believe a number of Samsung users are experiencing problems with the newer versions all focussed around the tab system.

After March or Febuary I think? Bookmarks become incredably slow. My device is a S20 FE rooted using U.N.1.C.A ROM and using Snapdragon 865 processor. It took roughly 80 seconds or more just to open the main bookmark folder. I also have big bookmark folders but it worked fine on the last update. I came across a Reddit post with similar situation: https://www.reddit.com/r/firefox/comments/1rhe8a5/bookmarks_are_a_lot_slower_to_change_location_on/ This is all I can gather

I was told to post here by mozilla dev from google play

I have an issues while typing certain phrases for example: 1-while typing "8oh" after typing "h" it autocorrect to "88oho" and place cursor behind last "o" so result looks like "88oh|o" where "|" is the cursor. 2-while typing "34-34W" after typing "W" it autocorrect to "34-334-34W4" and place cursor behind last "4" so result looks like this "34-334-34W|4" where "|" is the cursor. It is occurring everywhere like in search engine Google, while typing comments on YouTube and even in this particular window while typing about this issue. It does not occurre in adres bar. It does not occurred while writing without text prediction. It occurred even autocorrect is disable.
