Firefox Community Forum

Greetings support team. The problem is a bit complicated and I could't find anything similar to it on the net, so I'll try to explain in details what happened. One day after opening the browser I noticed that it didn't launch(there was no window). After opening it again I saw that all of my previously opened tabs were gone. After that I closed Firefox and went to check the task manager. I found that Firefox was still running after closing it. I couldn't wrap my head around it and killed the programm. Then I opened it again and got the same results: first launch: no Firefox window(nothing on the taskbar either), secound launch: one empty tab. After that I opened a new tab in Firefox through task manager and my screen "swiped right", I got access to Firefox window with all of my previous tabs, but all the other programms I had opened on the taskbar were gone. Somehow Firefox opens outside my screen on a "separate one" every first time I launch the app, and the only way to switch between "screens" is to open a new tab through task manager or launch a program that was previously active to switch back to previous "screen". It is also impossible to switch between opened windows on different "screens" using gestures on the touchpad or "Alt" + "Tab". I use a laptop and never even tried to attach/connect a second monitor. I don't have another monitor attached via bluetooth or any other means in device manager. I have the latest verion of windows 10 installed and updated. I have another PC, where I use the same Firefox with the same addons on the same Mozilla account, which has no such issues. I have tried renaming the file called "xulstore.json" to "xulstore.old" or deleting it entirely, this didn't resolve the issue.

When I'm clicking "Copy Link Without Site Tracking" on Facebook, I'm getting a very long link like: [0=AZXHU5Fm3iETylzElY4qHRw27uWnI_VbYwCYYbj6x6BPjGaj_yfVTLR8fIvGILOGciQm0_XpeFu6uqxnV147PjmDPArCU4fCaydKmZ6_0BAp3j7mfUtGQhNPJQKsjPAK1sN0M7CjPgKHhIlL7_Mb2poXSVjQwF_nMhqHO7Xc_XTtdLQw9hxaPV5qUcKm8rbrWus&__tn__=%2CO%2CP-R https://www.facebook.com/PilsetaCilvekiem/posts/pfbid0EqFQ5TwTkHeowowTc7ArY8T7ATCjxXvWiUzXJeDxCjCcQHFwt4h8PK9eJaEiaYiml?__cft__[0]=AZXHU5Fm3iETylzElY4qHRw27uWnI_VbYwCYYbj6x6BPjGaj_yfVTLR8fIvGILOGciQm0_XpeFu6uqxnV147PjmDPArCU4fCaydKmZ6_0BAp3j7mfUtGQhNPJQKsjPAK1sN0M7CjPgKHhIlL7_Mb2poXSVjQwF_nMhqHO7Xc_XTtdLQw9hxaPV5qUcKm8rbrWus&__tn__=%2CO%2CP-R].

Would it be possible to remove URL parameters "__cft__[0]" and "__tn__"? Because https://www.facebook.com/PilsetaCilvekiem/posts/pfbid0EqFQ5TwTkHeowowTc7ArY8T7ATCjxXvWiUzXJeDxCjCcQHFwt4h8PK9eJaEiaYiml opens the same post.

Have been unable to view readers comments for a number of weeks and can figure out how to fix. it is not all the time, like last night were available but not this morning. All other browsers there is no issue including DuckDuckGo. Am using Ublock Origin, but have been using for years with no issue, even when turn off result the same.

I discovered two issues with Firefox on my Wayland Gnome. Picture-in-picture windows should be opened with the "always on top" attribute, but in Wayland they are not on top. It's not a big deal to manually set always-on-top. Although I need to remember to do this after the window appears. The second problem is related to selecting multiple tabs. I should be able to detach selected tabs from the window by dragging them from the tab bar. A new window is then created with the selected tabs. This doesn't work in my Wayland. I can detach one tab, but not multiple tabs at once. I can still move multiple tabs from one window to another open window. So, as a workaround, on Wayland I need to open a new window and then move the selected tabs there. Which is inconvenient. I am curious if anyone else noticed these things on Wayland. There might be something wrong with my instance of Wayland.

Dear Firefox Team, good morning.

I hope you are doing well and that you are all healthy.

Guys... while looking for a way to measure the performance of our site, we came across the Core Web Vitals (CWV) some time ago. These are Google KPIs for measuring the user experience on a page (https://web.dev/vitals/#core-web-vitals). Unfortunately, some of the KPIs (like the Largest Contentful Paint or Cumulative Layout Shift) are currently only accessible using Chrome and it's preformance API. That's a pity, because there are also many people using Firefox who visit our site... and it would be interesting to have such KPIs as well.

In an article by Cloudflare (https://developers.cloudflare.com/analytics/web-analytics/understanding-web-analytics/core-web-vitals/) we recently learned that Firefox is also planning to expose the metrics used in the CWV... only the "coming soon" from the article is a bit vague. That's why I'm contacting you to get some more information on that topic. Do you perhaps know whether the topic is planned and will be tackled this year?

Thank you for your attention. Best regards, Carlos

I am getting multiple pop-ups from Mozilla. When I close them they continually pop up again. They are warning me of a 'system Alert' about infection or virus. click on them they are trying to sell me Norton anti virus products. I have Mcafee and its showing no problems. How can I get rid of these annoyances? Thank You

I don't really know whether this is a FF problem or Google Docs problem but either way I wanted to ask for help here. When I try to install any extensions on Google Docs it redirects me to a blank page and after a few seconds it says "The page isn’t redirecting properly" and doesn't install the extension.

Windows 10 pc can not start,I have gone through automatic repair and diagnostics steps,but am now on advamced options and think I need to Reset it.This will lose Firefox.When I install it again will I be able to sign into my Firefox account to retrieve bookmarks and passwords?I am very nervous about this,don't even know how to install Firefox,as someone gave me the computer and it was already in there. I am a tech dinosaur!Thank you in advance for any help.Lesley

I expect the back button to return to the previous page visited, but too often the button either doesn't respond at all or a right click is required to view the page history. Is there something I need to do get the original function of the back button that I thought was universal in most browsers?

I am trying to edit /etc/hosts file. CLI utils respect the values that provided there, Chrome also.

But the Firefox continues to ignore. I have disabled "Enable DNS over HTTPS using:" and turned it off.

But it doesn't help. What else could be done?

Hello,

A couple of months ago I discovered that I no longer have the ability to edit, delete, or dismiss a shortcut from the home page of my desktop. I did read that the 3 dots will appear if I hover over a shortcut. I tried that several times on different shortcuts but the 3 dots never appeared. Is there another way to edit, delete, or dismiss a shortcut? Or even better is there a way to restore the 3 dots?

I cleared my cookies, cache, history and data like I was told to when I connected a new router so all of my shortcuts have changed. A few that are there now I don't want and I do want to add several new ones.

Thank you for your help!

Any help to fix this would be much appreciated

I have tried restarting both firefox and my computer, disabled all extensions and started firefox in safe mode. When I try to right click on a firefox window from the taskbar it just disappears.

I have my computer connected to my TV so often when I open it up some windows will be on my TV which is behind my desk so its a pain to move them back without this function.

Hey all,

Last night I made the mistake of clicking a sketchy link on twitter thinking what it was some meme site( the person who tweeted is someone I know personally so I thought it was safe) once I clicked on it, I wasn’t redirected to the site so I thought it was weird then once I learned that he deleted it because it was compromised. I got scared and I was running scans through Microsoft defender. After the full scan it said that it detected Trojan:HTML/Phish!pz and the affected files where C:\Users\….\Local\Mozilla\Firefox\Profiles\cq0glqqq.default-release\cache2\entries. I deleted my cache a few hours later than I should.

So I reached out to a friend and they told me that it was probably was a false flag and I didn’t need to delete my cache. But I’m nervous that it’s an actual threat and I should do more to ensure my computer is completely safe. Also probably a lot of grammar mistakes I haven’t slept since I got this information.

Hi, I can't use Firefox because a captcha won't complete loading. I have uninstalled and reinstalled, cleared cache and disabled add ons. I am using a vpn (PIA). Chrome and Edge both load and operate OK. Thanks in advance.

Captchas are an ongoing issue. Firefox seems to have a LOT more captchas than other browsers. Is there a problem between Mozilla and Google?

I've got my "homepage and new windows" setting set up with several "ext+container links so that my selected websites open in their respective containers : e.g. ext+container:name=Personal&url=https%3A%2F%2Fwww.facebook.com%2F%3Fsk%3Dh_nor

I open facebook in 2 seperate containers so that I can maintain 2 seperate personalities under facebook - e.g. I am a group admin within one, just a group member in another.

I have 2 urls defined in my "homepage and new windows" setting for these :

ext+container:name=Personal&url=https%3A%2F%2Fwww.facebook.com%2F%3Fsk%3Dh_nor ext+container:name=Facebook&url=https%3A%2F%2Fwww.facebook.com%2F%3Fsk%3Dh_nor

This was working fine without any issues. My sites opened up when I started my web browser and everything.

Recently, firefox has started up but my container tabs do not load automatically, I am getting a confirmation (I will post a screen capture as a comment).

Is there a way to turn this off and just open the tabs without a confirmation?

I need to change my email address as my provider is closing down. I have seen the suggestion that I make a secondary with my new address but this will nor work as I have the secondary address with the same provider.

Firefox View Open Tabs is my favorite feature. I (used to) use it daily, but now, even though I have NUMEROUS windows (over 40) and multiple tabs in many of those windows, View Open Tabs is completely empty. I'd very much like to restore that 'index' without losing all those pages/tabs (it's my reading & ToDo list).

Sometime recently, I found it using gobs of CPU even though Javascript was (and still is) disabled, so I found the top CPU process and killed it. Instead of a single page going blank, Firefox crashed. Sometime after that I noticed that View Open Tabs was no longer populating. Maybe that contributed or instigated the dysfunction?

Mozilla is great at pushing out every possible new update, no matter how trivial. Every time it does, I have to reset everything.

I've been doing this since Firefox 6. I've learned to store all my about:config tweaks in a file so I can quickly copy, paste and reset them on each update. I've included the various program settings I want, too, so I don't have to think and try to remember what each one means and what I want. I use userChrome.css to set some of my display settings, but I'm not very familiar with it.

Is there some script, program, add-on, or other method to convert this time intensive restoration of my settings every month or so for all the new updates. I'd love to find some form of a "registry.reg" type file that would work on Firefox and/or Thunderbird.

If there's something out there, I'm positive a LOT of others would want it, too.
