Hi, I often use the "Take a screenshot" feature, but I have noticed that it does not work on some sites. For example, when I try it on https://www.thetrainline.com/ , nothing happens after I click the button "take a screenshot". What is the cause of this? Is it a problem with the site itself or with Firefox? Thank you!

Firefox 78.0.1 does not remove closed pages from memory - lags and high RAM usage

After updating from 77 (I think it was 77.0.2?) to 78.0.1 I started noticing terrible firefox performance after a few minutes of browsing. My standard browsing habit consists of launching browser with 1 pinned tab and 1 home page (so 2 tabs only), then opening 5-10 tabs from my bookmarks, checking pages then closing them and leaving only 1 pinned page open. In firefox 78.0.1 after doing this (opening and then closing multiple tabs "to the right" using new context menu added in 78) my ram usage does not drop. It goes from 2.4GB (system only usage) to 5.0GB and does not drop after closing tabs. However when I open 10-20 tabs again RAM usage does not rise (maybe slightly, like 5.3GB). So it looks like firefox has multiple tabs stored in ram and opening new tabs just rewrites that memory instead of allocating new one. I have 8GB of ram so 3GB of usage from 1 open tab is crazy. I think it was 500-900MB before. I also have terrible lags because of this - browser hangs up every few seconds for few seconds. I had trouble writing this post with 2 tabs open because of 3.3GB ram usage! Restarting browser helps - ram uasge rises from 2.4GB to 3.2GB only (800MB for 2 tabs) but every new opened and closed tab seems to stay in memory. For example if I open 10 more tabs except for 2 that always open so I have 12 tabs I have 3.6GB memory usage. After I close them it slowly drops to 3.5GB instead of returning to 3.2GB. It does not matter how I close tabs - using right click context menu (close other tabs, close tabs to the right), using X on tabs, or using add-on to close all tabs except for pinned ones. They always remain in memory somehow. PLS fix this ASAP.

P.S. I also tried checking about:performance menu but there is nothing interesting here. It says that 2 opened tabs and addons use 100MB of memory which is not true because browser at this moment uses 1060MB.

Update 1: I also tested safe mode. 3,4GB of PC RAM usage on firefox safe mode start. Opened few tabs, ram usage goes to 4.2GB. After closing all tabs except for 1 ram usage start to SLOWLY decrease but it stops at 3,7GB. Ram usage drop was really slow like 10-30 seconds. It should be instant after closing tabs.

I'm using Firefox 78.0.2 and i keep getting notices to upgrade. But the last time I upgraded, Firefox changed the locations of my tabs from below the address bar to above the address bar and also changed the behavior of the address bar. It took me a couple of weeks to find the answers and get things back the way they were. I don't want to upgrade Firefox because I have no idea what it might change this time. Is there a way to keep Firefox from sending me upgrade notices when I don't want them?

Up until recently I was using a 11 year old laptop that was slowing dying. I was finally able to acquire a new computer and get it up and running just before an accident (as if out of a comedy movie - the roommate's cat knocked a full bowl of cereal onto the old laptop) effectively destroyed the old machine. Thankfully, Firefox Sync meant that everything I had been working on appeared when I got the new machine fully functional...until I logged on to Firefox this evening to find my Synced Tabs empty with just a "Want to see your tabs from other devices here? Connect Another Device" message.

The old device is toast...I don't know if it will even turn on again, much less function enough to sign into Firefox. Synced Tabs was also working just fine for a solid week until it just up and disappeared. Is there some way to restore these? I know it's my fault for relying/expecting Sync to always be there and not backing up the links I had open immediately, and this is a mistake I won't make again...but I'd really love to not lose everything I had open.

Thank you very much in advance for any help or suggestions.

Dear Colleague,

  I am on a Surface Pro 3 running Windows 10 64-bit.     I have been running Firefox for 15 years without a problem. So,  I saw that there was an upgrade to Firefox, and I downloaded it and started installing.    I have completed this process many times in the past.
  When I started running the upgrade, I received the following error,  XUI Runner window that says  "Error Platform version '78.0.2' is not compatible with minVersion>=78.0.1 maxVersion <=78.0.1.  I checked the wiki and the bug list but did not see any bugs.    
  I have not uninstalled and reinstalled yet because I do not want to lose my bookmarks, history, etc. if I can help it.  
  Any help would be appreciated.

Thank you Marj

I have a bookmarks menu link on the bookmarks toolbar. When I save a new bookmark to one of the folders it does not appear. It does appear when I click on the saved history icon. However, if I open the bookmarks sidebar from the history icon and navigate to the same folder, the new bookmark appears but it is missing many other bookmarks that are in the other folder.. I can also save the bookmark to the toolbar and it appears there. Also I can cut an paste the bookmark from the toolbar to the folder. I've tried disabling add-ons and that doesn't fix the problem. There clearly are two sets of bookmarks. How do point Firefox to the one I want?

I was trying to stop websites from reloading pages automatically so i setted: accessibility.blockautorefresh = true and browser.meta_refresh_when_inactive.disabled =true. Now many websites when loading , shows at the top of the page a warn strip: " Firefox prevented this page from automaticaly reloading " , and also there is an "allow" button. In the older Firefox versions it was a preference in about:preferences#advanced page: " warn me when websites try to redirect or relod the page " and i was kept it unticked , but now i can't find it. Is there any way to keep stopping websites from auto reloading , but not shown this annoying warn ?

In Manage Data, I can see which cookies are used by which sites. If I want to sign in to a specific site automatically while still generally deleting cookies when I turn off Firefox, then I need to list all the cookies used by that site in Manage Permissions as Allow. This is easy regarding sites that use cookies all with pme common domain, since you just enter the one domain name. Today I wanted to preserve cookies from a major newspaper, but I find at least five domain names in the cookies that I have to protect in order to enable auto sign-in for that one site. My suggestion is that there be some improved method for easily 'transfering' (rather than writing down and re-keying) selected cookie domains from Manage Data to Manage Permissions, instead of having to rekey them and make errors doing that. If I want to auto sign-in to 15 sites, but keep the controls set for deleting unprotected cookies when closing Firefox, I would have to enter perhaps 75 domains by hand. An alternative might be a column in Manage Cookies whereby I could check mark a cookie, thereby transfering it to show in Manage Permissions, perhaps as defaulting to Allow for Session. Then I could review them and if desired switch each to Allow.

this extremely annoying hyperlink tool tip pops up and gets in the way of mouse clicks. if im not careful I'll accidentally click it instead of what i intended to click on. it likes to pop up over my email check boxes too when im trying to select mail to delete. if i do accidentally click on it, it will follow the link using the tab im currently on which is the brunt force of the annoyance. it absolutely gets in the way and infuriates me to no end. I dont have any add-ons that specifically relate to it, and i cant find anything doing a google search that relates to it either.

Hi, I'm trying to access to audio and video website like Spotify (Audio) and DisneyPlus (Audio + Video) but a yellow bar on top inform me to try later because necessary component for audio and video is installing.

This issue is present since different day, I tried to reinstall, reset Firefox but the issue persist. Windows 10 2004, Firefox 78.02.

Why no issue with the browser and Firefox should show a banner and ask to try later where the situation is the same? Why Firefox is not allowing me to watch video and to listen audio now?

I hate Firefox when do this... it's not intelligent.

A lot of folks are having issues with the new URL bar.

My biggest issue with the new URL is the way that URL bar text turns light blue rather than to normal way that selected text is shown, in negative (white on blue), because I often want to select part of the URL and the light blue makes it difficult to see what I have selected. I am 55 and my eyesight is not what it used to be.

jscher2000 kindly recommended adding the following to userchrome.css here https://support.mozilla.org/en-US/questions/1283831?page=3#answer-1331668 as follows

  1. urlbar {
 --lwt-toolbar-field-highlight: Highlight;
 --lwt-toolbar-field-highlight-text: HighlightText;

}

But this css does not seem to work for me.

I have not touched the Firefox theme, so I guess I am using the default theme, but I have added the multi-row tabs css from MrOtherGuy https://github.com/MrOtherGuy/firefox-csshacks/tree/master/chrome/multi-row_tabs.css but the multi-row tab css does not seem to mention "toolbar" so I can't see that they would get in each other's way.

I would also like to turn off the automatic selection of the whole url but that may not be possible.
