Hi to All I am user of firefox on several windows 10 computers, probably 7 different computers. I want to point out the huge memory usage in firefox on absolutely different computers and I want to resolve this brainless problem. At beginning, probably in 2016 I began to notice big memory usage in firefox with many of tabs opened, probably over 100... yes, 100 tabs is too much but even so, memory usage seemed inappropriate to me, especially when before it working on computers with low memory installed. I started solving huge memory usage by restarting firefox, usually killing firefox through taskmanager on windows. But about a year ago I started using Firefox on several computers for loading some pages and I programmed automations of some tasks on this pages. This tasks includes clicking on buttons on pages, entering values and loading new links, subpages.... This all always in one tab and in one firefox window and after some time, firefox on every computers start using over 3GB of memory, in one tab and one window??? It is galactic amount. Of course, processes on computers was crashing. Depending on the page, that was severed from 12 hours to several days. Therefore I started some researching in this and I tried to reduce memory usage by settings in about:config: browser.sessionstore.max_serialize_back = 0 browser.sessionstore.max_serialize_forward = 0 browser.sessionstore.max_tabs_undo = 0 browser.sessionstore.max_windows_undo = 0

browser.sessionhistory.max_total_viewers = 1 browser.sessionhistory.max_entries = 1 but this last parameter have no effect, why??? After this settings my solution working, but it is little bit breaknecking: After some steps in automation I open new tab and close prewious tab and load page again and memory usage drops from 1,5GB to approx 500MB (Due to browser.sessionstore.max_tabs_undo = 0) Excuse me but this behaviour is very terrible.

browser.sessionhistory.max_entries I trying to reduce to 1 but this setting have no effect (I can back to new tab page), sometimes take effect only in just running instance when I change it and number must be higher than 5 or 10? Sometimes take effect, sometimes no, but after restart firefox again without effect. Due to this nonsense memory accumulation per each one tab I want to tweak firefox on my working computer. I not need galactic number - 50!!! or even more? pages in "back button" in memory per each tab, and there are no way to reduce it without restart, only way to release memory is set browser.sessionstore.max_tabs_undo to 0, open new tab, and close old tab and then memory usage very drop...

Next, I searched in about:config by keyword "session" and found browser.sessionstore.cleanup.forget_closed_after default equals to 1209600000 which means 14 days... oh so galactic... Normally firefox is unusable after few days without restarting, developers recommends to restart firefox for memory free up, but default value for this option sets to this huge number? Are they kidding users or what? After all, with this setting and behaviour, it almost never applies. And how much such nonsenses does firefox still contain? I am very angry for this several-years lasting memory issue because firefox is my favourite web browser. According to what I found on the internet, developers stubbornly ignoring or refuse to find effective solution but it would be so simple. Probably only memory release button would suffice, which would remove all cached pages. But "true release/free up memory button". User would had to accept, that all back/reopen actions will be discarded. No dummy/parody button in about:memory. ooooh "minimize memory usage" which free up probably max of 15%, normally about 5% of used memory. I tried "firemin" too, but this is next parody... this rapidly decrease of memory which appears as super, but causes totally pause of processes on page and when you need do some action on page, another time is needed for reloading(wake up) the almost same amount of memory as before minimization by this program - in short, this is suitable just only for temporary minimization of memory usage, something like pause firefox.

Therefore please, Can someone really help? (Not kidding like: about:memory, firemin or other unusable "nosolutions") This problem has been consuming me for so long that I quietly started to think that the only way to resolve it is to reprogram and recompile my own firefox, but that is quite unrealistic for me.

we use firefox with tablet and second bigger monitor. caused by last update the visibility at second bigger monitor is not sharp any more and the letters of all text are broken. In the paralle running tablet monitor all is best. All other apps did not have this problem.

How is it possible to change this ?

After installing Ubuntu 20.04 LTS Clicking on Firefox or Thunderbird it hangs the computer and have to switch off the computer on main switch. Reinstall Mozilla once but no difference still hangs Ubuntu. Need help on this one Thank you

When I click shift and right click always a context menu comes up and I would like to deactivate that. Concrete: I would like to draw arrows on a chessboard (lichess.org) with shift and rightclick, but then always a context menu comes up and distracts. This is very annoying and I would like to change that - though what I found so far wasn't that helpful for me.

Thank you very much in advance

Ok, so like the title says.. Years ago, Firefox changed from having the normal "File Edit View History" etc. as the default interface and tried to streamline everything into icons. I have no idea why. Maybe it had something to do with the mobile version. With a few customizations I was able to get the old look back, with my address bar.

Then a while back the address bar changed. It used to be that the address bar had a drop down that listed the sites you used most frequently. At some point mine just sortof froze and only lists the same 8 sites. Except its worse because 2 of them are now searches for Google and Amazon and not even the original google or amazon web pages. I cannot delete pages from this list like I could in the past, either.

Also, you could, you know... put an address in the address bar and it would take you directly to that site. Now it tries to do a search just as often as it actually takes me to the correct site.

This forcing search engines baffles me, because there's an actual search bar, right directly next to the address bar by default.

So if someone could help me understand how I can change my address bar back to being an address bar, that would be a great help to me. Second, if I could fix the drop down of sites to either be my most frequent sites, or a list of sites I add manually, that would be great also.

tabs not working:

Click on the tab but nothing comes up. the audio for you tube is playing but can not access it.

Click on the firefox I con and the tab buttons appear but click on them nothing happens. thanks

I had a folder on my desktop that I created a couple months ago and then deleted. However, for some reason it keeps coming back, and I've discovered that it happens whenever I download something. This seems to happen regardless of where I save something or where the pop-up for choosing the download destination automatically opens to. It also seems to be specific to firefox, as this doesn't seem to happen with other browsers.

I should add that it's only the folder itself that comes back. Before I originally deleted it, I emptied its contents and it's only the empty folder that keeps reappearing on my desktop

I have three FF profiles on my Linux Mint 19.3 system (work, not-work and one for e-tail). Somehow the problem only appeared after I added that last one. All profiles have the same syntax; I checked the files. Neither one is set to be the dominant one. Typically, I don't use more than one at a time.

I also use Claws mail. Whenever I get any mail with a link I want to check out, I just used to click on that link and it opened in a new tab in the FF browser profile that was currently open. Similarly, whenever I wanted to see the HTML version of a mail, I right-clicked on the html-icon and chose open. Again, it picked the open browser.

Now, though, whenever I pick either one of those options above, I get the "Choose User Profile" box. If I pick the profile that is currently open, I get an error telling me that it's already running.

Since I mostly read email when I use the no-work FF profile, I tried to add "firefox -P NotWork -no-remote --class NotWorkProfile" but that also resulted in the choose user profile box to open.

My current work-around is to copy the link and open it in a new tab, or pull the whole mail into the tab to see the HTML version. Quite annoying.

Is there any way to get it to ignore all other profiles but the currently open one? Thank you for anyone who has an idea. Let me know if there's anything else I may add to explain the situation.

[My apologies if this isn't the right forum; I'm also attempting to ask this question in the Linux Mint and Claws forums, if those exist.]

There are ongoing discussions about the high touchpad scrolling sensitivity on several Wayland applications like Firefox. Luckily, I found a workaround with this issue by setting `apz.gtk.kinetic_scroll.enabled` to `false` and increasing the default value of `general.smoothScroll.mouseWheel.durationMinMS` from `50` to `120`. However, there is still minor quirk with my scrolling experience especially at the end of each scroll or each time I pause scrolling.

This minor quirk has a lot to do with how I do the two-finger scroll gesture. For each scroll, I don't necessarily lift my fingers up immediately. I might pause for a while then scroll further until my finger reaches the end of the touchpad or I might scroll in the opposite direction without lifting my finger up. However, just having two of my fingers rest on the touchpad detects even the slightest movement. The effect is a page slightly shakes each time I pause scrolling without lifting my fingers up. Although, this minimal shake also occurs as I lift my finger up.

This behavior is detailed in a bug report here . It might have something to do with Wayland but based on my experience, the issue still persists when running Firefox through XWayland. Also, Vivaldi (Chromium) which also runs in XWayland, doesn't show this problem. In Vivaldi, the touchpad will be less sensitive (at least that's how it feels for me) each time I pause scrolling.

I already tried fiddling with the following through the `about:config` to no avail:

• apz.touch_move_tolerance
• apz.touch_start_tolerance
• mousewheel.transaction.ignoremovedelay
• mousewheel.transaction.timeout

I use Firefox 87 on a number of notebooks duel booting various distros of linux (Mint, Manjaro, and MX Linux) and Windows 10, as well as a desktop running Windows 10.

On the notebooks Firefox is set to always use private browsing mode in both linux and Windows. On the desktop machine it isn't, but I always have private windows open. On the desktop version of Firefox private windows have the purple circle with a mask icon to show they are private. On the machines that are set to always use private mode Firefox never shows that icon, so I have to go on faith that they are private. Is there a reason always private doesn't also have the private icon?

Also, on the machines where Firefox is launched in always private mode, it always open 2 separate windows. This is a consistent thing when in always private mode.

Firefox Dev Ed is a great browser for web development and tweaking CSS. But sadly it does not always show default property values.

element's default padding-left property. This apparently is set at 40px automatically unless overridden by the web designer. I think that ALL inherited or default properties of elements ought to be clearly shown in the inspect tool's styling listings. You could spend hours maddeningly trying to find the cause of some of these offsets to what you expected to display. The curious thing is that some inherited or default property values are shown on the inspect tool - which leads us to assume that what is seen on inspect is all that there is . . . This change should not be too difficult to implement. And it would be a great thing to have when searching down unexpected behaviour in webpage displays.

On a number of sites (YouTube, Twitch, Netflix, etc), after pausing and resuming a video or jumping to a new timestamp, the video will play but be muted. The video player does not show it is muted, but no sound is playing. Jumping to another timestamp or using a keyboard shortcut to jump a couple of seconds will resume audio playback. This started happening within the last few days. Any ideas on how to fix this would be appreciated

Long story short, I have gaps in my history in Firefox. I'm on the latest stable desktop version, but this happens both on Linux (Ubuntu 20.04) and Windows 10.

I can't really pin down what causes this, it seems totally random. Every now and then, I'll be browsing, close the browser, realize I need to do something on a page I was recently on, I relaunch, press "ctr+h", go to the 'Today' drop down tab, and the most recent entry is multiple hours old, in some cases it's not even from the same day. The pages I was just on are nowhere to be found.

I would guess it's just late to update the history, but then there are times where I'll go through my history from a few days ago looking for a specific page I know I visited, and I'm able to find some but not all. Again, it just seems like there are random gaps in my history.

When I search my bookmarks with *, instead of my bookmarks showing on top and selected, always "Search with DuckDuckGo" on top and selected. I want to write my bookmark keyword and tap Enter to reach the website. Is this possible?

Morning, got a question for you: since i surf on mozilla on mac (expecially on youtube with full screen video mode active) can't get any system notifications (as messages, incoming calls, etc), the "do not disturb" icon appears on the menu bar. Least but no last, one of my mozilla extensions is you tube enhancer, shall i change any options there? Please help me to fix this annoying issue. Thanks
