Hi, currently I opened many tabs in Firefox with tree style tab. Recently I found that my session not restore to the point I closed it but the specific time. (In this case, the session I close on 2020/03/12). For the tab I opened/closed after that seems not be stored. I also checked and found that the sessionstore.jsonlz4 was not updated. As my knowledge that this file should be removed when Firefox executed but it seems not. I may wish to ask if there is any solution to fix this problem while keep my current open tabs. Thanks for the help.

Upon double clicking my email msgs, I used to get a pop-up showing the entire message. Now, when dbl-clicking on the msg, a pop-up comes up, but the entire page is black and no message is showing at all. This just happened upon the latest Firefox 64bit for Windows10 having downloaded. I also added my email website as an exception under "block pop ups" in Firefox.

Recently Firefox has become nearly unusable. Opening links are *_sluggish_*... They eventually complete but it's annoying - I've switched back to brave for now. https://support.mozilla.org/en-US/questions/1175357 seems to be the exact same issue however nothing in the thread resolved my problem.

I'd like to stay with Firefox but it's not worth it at this time. :(

Any thoughts/help are much appreciated.

Instead of having my bookmarks under the toolbar, it's along the left side. I have many things in chrome.css, like one that gives me 4 rows of bookmarks, but on the side, it's only one. If I click on one of the ones I can see, it does go to the website, as I can see the correct url in the address bar. However, everything is blank. Even about:config is blank. Safe mode works, but of course doesn't give me my bookmarks or anything else. The extensions that Safe Mode says are disabled are: Amazon Assistant for Firefox, Dashlane, and New Tab Override. Do you need the things from chrome.css to help me troubleshoot? I can't keep using Safe Mode, don't care for Chrome, and refuse to use IE.

I have the Norton Password Manager (PWM) extension installed. When I want to log in to any protected site for which I have already stored the login info, I have to log in to my Norton account before I can log in to the PWM itself.* The box for that has a checkbox "Remember me on this device," which I leave checked, but if I close Firefox and open it again, the box pops up exactly as before, whereas on Chrome, the login info is entered already. I have tried restoring Firefox to its default configuration and entering the Norton login info on both the logins page and on the cookie exceptions page, but nothing works. What's up?

  • This seems to be a relatively new requirement by Norton, which I already explored in another thread.

Following the recent update of Firefox I can't access my Gmail account. The Gmail tab is there but clicking on it the screen stays blank. All other tabs, such as weather, bank etc., are working as expected. I can access my emails if I change the browser to Google Chrome but Firefox is my default browser and I would like to keep it as my default.

I've searched and found something about profiles, but when I installed Vue.js devtools on DE it installed on normal version too. Can I separate it in any way keeping everything on one account? Best

I've just been customising Firefox's look by selecting the dark theme (which appears to be the only way to get some things like the dark NTP), then using userChrome.css to alter various elements to what I want. I don't actually 'know' CSS but searching has found the code to copy into my userChrome.css and then edit the colour values for almost everything. I've changed the toolbar, tabs toolbar, url bar, bookmark bar, menus, context menus, everything I wanted ... except one thing. The background colour of the active tab (just the actual tab in the tabs bar) is stubbornly staying the colour it gets from the Mozilla Dark theme, and I want to change it to the (slightly different) shade of grey that I've changed the toolbar to. Can somebody please tell me what the lines are to put in userChrome.css to change the background colour of the active tab? Thanks.

Latest reason why the "don't let Flash run automatically" decision was a FAIL

Once again, we have a new release (74.0). Once again, the developers who believe themselves to be gods do not think users should be allowed to set Firefox to allow Flash on specific sites without asking EVERY SESSION, somehow believing that inconveniencing the users is somehow going to force website admins to move away from Flash before the announced deprecation at the END of the year.

Now one of my daily-visited sites (the one for Daily Jumble) will not wait for me to enable Flash, and when I do enable it I then have to refresh the page to make it work. It is obvious that if what I have been asking for all along -- being able to tell Firefox to enable Flash always FOR THIS SITE ONLY -- would alleviate the problem, but since the gods cannot see through the eyes of the users, I am now further inconvenienced by their decision.

I maintain that they moved too quickly and too drastically to implement this change, and I have no reason to believe posting this will make any difference, but I again want them to know that instead of Firefox being the most user-friendly browser in the world (as it USED to be) it now has enough user-UNfriendliness to be as despised as Internet Explorer was.

I do not believe it to be an unreasonable request to allow this, because they could simply put that functionality in, then take it out along with all Flash support in the first release of 2021. But they think they know better. Sorry, guys, but you DO NOT.

How to set Bookmark to always open in a container

The option to always open a link in a particular container seems to be linked to the domain; right-click link, Open link in new Container Tab, click the Always open link in this container. This then sets all links to that domain to open in that container.

Often I want to log in to the same domain, but as a different user. So I open them in different containers so as to keep the sessions separate.

It would be useful to specify the container in the bookmark rather, so I can have multiple bookmarks all pointing to the same domain, but each always open in the container I choose for them. I tried various add-ons, but they use the domain-based container feature built into FireFox.

How can I force a bookmark to always open in a set container?
