How to install Firefox Developer on Linux (Ubuntu)?

I tried the manual way:

https://medium.com/@js_debugger/how-to-install-firefox-developer-edition-on-ubuntu-1c7f5f2b6883

but it does not seem to work for me.

With the 91 version of Firefox my home website no longer displays correctly.

If loaded via Edge and previous versions of Firefox, it has displayed correctly on Firefox for years. Something in the 91 version doesn't like the website. www.lonespruce.net

Did this version develop a dislike for website using PHP?

After a refresh of Firefox I lost all of my bookmarks. I have tried everything that online support suggests but nothing I do works. Please help! I have years of bookmarks that are very important to me.

Thank you

When I open Firefox I want different tabs to open. In the past there was an option for adding different start-up pages but now under settings I cannot find it.

There doesn't appear to be anything recent under the help pages.

Also, on another point, the settings menu in Firefox seems to be much more basic now with lots of settings hidden, you have to type in what you want in the help box, I don't understand why Firefox do this we should be able to just scroll through all the different options available under settings

Hello, I switched to Firefox from Chrome, however, the browser is missing one of the most important features I use almost all the time - swipe left to go back and swipe right to go forwards. I checked about:config and browser.gesture.swipe.left is set to Browser:BackOrBackDuplicate but it does not work. All answers on Mozilla Support and elsewhere are outdated or do not answer the question at all. Please fix this, it is the reason why I switched back to Chrome twice before. Any help is appreciated.

Hello,

Every time I log in to Outlook.com in Firefox a pop-up automatically appears below the address bar. The persistent pop-up: Add "outlook.live.com" as an application for mailto links? See screenshot attached.

Troubleshooting and modifying Settings to eliminate pop-ups and recommendations didn't stop the pop-up. Deleting Firefox beta and installing the standard version of Firefox didn't work either. The only way to manage this pop-up is to click on the "X" button to close it each time I open or refresh my Outlook.com home page. Then I get some screen space back.

Using Edge, the pop-up includes other options to choose from such as "Don't show this again", which I selected. I don't see the pop-up any more in Edge.

Why can't I get rid of this unwanted, persistent, recommendation pop-up in Firefox?

Thanks, Gordon

I imported my bookmarks from a windows 8.1 computer to Parrot Linux Debian desktop (2 different computers). I am missing the everything from 'Other Bookmarks' after I imported it into the Linux computer, I can see all everything from 'Bookmarks Menu' though. The windows machine is not working anymore. But I have a saved copy of all the bookmarks from the windows 8.1 computer.

Is there a reason my import left out the Other Bookmarks but imported the Bookmarks Menu? How do get them into the linux firefox browser.

Firefox 78.15.0 oesr Linux Parrot home edition OS version 4.11

Thanks in advance

How do I turn off an ad blocker on firefox. I have an app that will no longer function and tell me to 'turn off the adblocker' to get my desired output. Help! Can't find it any where and search is no help.

Not sure when this started. But whenever i try to load google.com or when i click on my homepage which should bring me to google.com but nothing will happen. i will need to close firefox then reopen again then it will work. Then after sometime it will not work again. Have try to uninstall and re install but still no use. Anything i need to do to fix this?

I have noticed that sometimes the firefox browser crashes when a video is playing. This has happened multiple times now. To debug the issue, this time i started the browser using terminal so that when the browser crash i will see the message on the terminal. This time i was watching a youtube video. And while the video was playing the browser first hangs(meaning the screen/video freezes and browser doesn't respond to any clicks or anything) for first 2-3 minutes and then it crashes. This time since i had started the firefox from terminal, after the crash i got the following printed out on the terminal: ``` user@user-Inspiron-xxxx:~$ /usr/lib/firefox/./firefox Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. CPU time limit exceeded (core dumped) ``` I am using Ubuntu 18.04 and Firefox version 98.0(64 bit). I have downloaded the tar file of this version from Mozilla's official site and then installed it manually on my machine. Can someone help me solve the issue and also tell me the reason for this crash.

Dear Mozilla Community,

I have problems with one website. This website is poczta.wp.pl. Sometimes this can't be loaded. I see this error:

"SSL_ERROR_INTERNAL_ERROR_ALERT".

This is website with https protocol. What is the reason? Other websites works fine. I think that this is not problem with my router or internet provider because I changed both and it is still problem there. I had this problem also on another computer with Windows 10 operating system. I contacted with administrator of this website and they think that all is okay so they suggested me that this can be problem with browser or my computer.

This behavior is very hard to test because this issue is showed very rare. Sometime one time in one week and sometimes two time in one day. I don't know what is going on with this.

Can you help?

i opened firefox (v.95) and tried opening up my email and found that all my saved passwords were gone from firefox on my computer. it said i should crate a firefox account to get my logins back so i did and i still could not access any of my web logins. so i searched the help pages. opened up my profile n made a backup of my key3, key4, n loginjson files, downloaded v.91 firefox esr and copied my key3 file into a new profile.

so i still dont have my web logins ... n now i have an outdated version of firefox with none of my bookmarks either. im sick of troubleshooting n my wifi is almost out for the month.

how do i get my web logins and bookmarks back so i dont have to spend hundreds of hours recreating them?

Hi.

After the recent update of MacOS Big Sur to 11.5.2, my Firefox browser cannot display web pages in dark mode. I've tried reinstalling Firefox, reinstalling MacOSX, used Time Machine, changed Mac display settings, changed Firefox settings and nothing works. I've attached a screenshot of how my monitor looks after the update. The background is always white If anybody has a suggestion of how to fix this or what is wrong, please let me know so others can benefit from it if they have the same problem.

Notice the white background behind the number 1,2,3,4.

I cannot log in to my Google account with Firefox. I get this message: You appear to have no security keys registered on your account, and won’t be able to sign in. To sign in on this device, ask your admin about registering a new security key or choosing another second step for verification.

I am the administrator of my account on Google Workspace. I have no idea what the problem is. I have MFA turned on and I am able to log in to Google with Chrome and Edge. I don't see an option on the Google Admin security tab to create a new security key. Please advise on a fix. Thanks

I am using Firefox 98.0(64 bit) on Ubuntu 18.04 and it crashes sometimes while i am browsing. I have downloaded the tar file from the official site and then installed it manually on my system. To debug this this time i opened the firefox from terminal and waited for it to crash. After some time while i was browsing, it suddenly crashed as i expected. The output that i got after the crash on the terminal was: ``` user@user-Inspiron-xxxx:~$ /usr/lib/firefox/./firefox

Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. CPU time limit exceeded (core dumped) ```

What is the cause of this crash and how to solve it. After the crash i also typed: about:crashes on the address bar of the browser but when i pressed enter, i got a blank page on the top which No crash reports have been submitted was written.
