Is there any way to rotate between different screen sizes option using shortcuts keymaps which appear during "responsive design mode" is on. I found extensions which resizes whole browser & they helps. but it also causes developer tool to resize along with browser which hinders me to see different css properties. so i am looking for a way to rotate only screens.

"Responsive Design mode" is what turns on when we press ctrl+shift+m.

I Love using firefox more than Chrome. This is my go to browser.

Steps to reproduce:

1. Have Google as the default search engine.

2. Type a search string into the address bar.

3. The address bar briefly shows a URL for the Google Search results.

4. The address bar is very quickly overwritten with the original search string.

See screenshot for example.

How do I stop step #4 happening? I want the URL to remain in the address bar, for example to be able to give somebody a link which executes the google search.

I think this is new in FF121.

My Firefox account and associated passwords were left open on another notebook. I have now changed my Firefox sync login password from a different PC and signed out of other devices. Can a user on the previous PC sign in with a password that is saved in Firefox?

With 'Back up your Firefox data' it says it saves all open tabs.

What is meant by 'open' tabs? Is it tabs that I have clicked on during my session?

I have just over 300 tabs, will Firefox save all of those tabs in the cloud or only the tabs I clicked on during a session?

Hi there

Can not install google translate on my toolbar. When clicking the "puzzle" to access extensions google translate is there but it's greyed out, thus not accessible, when clicking on it there are no options to pin to toolbar as other extensions have that option, clicking on options if shows "manage extension" " remove extension" and " report extension"

I have a Lenovo ThinkPad X1 Yoga Gen 6 (20XY005MGE) with Win11 Pro.

All of a sudden, Firefox does not play any sound. I notice that it does not show up in the volume mixer. I tried:

• this solution: https://support.mozilla.org/de/questions/1278299
• Reboot the PC
• Uninstall and reinstall Firefox
• Deactivate all Extensions
• I worked my way through the manual pages (none of which mentions Firefox missing in the volume mixer)

Youtube does not play sounds, the Spotify page notices that it cannot play sound (the spotify App for Windows works fine, though). News sites (tagesschau.de / video, deutschlandfunk.de / audio) play the video, but no sound.

I had the problem a few months ago already but I cannot recall the solution :(

Thanks for helpful hints!

When selecting "Open in Firefox" in the "What do you want to do with this file?" box or on about:preferences and then opening a PDF file on the web, instead of downloading the file to RAM and opening it with its online address, Firefox downloads the PDF to /tmp/mozilla_${USER}0 and opens it from there. This also adds it to the download history. I have set the about:config flag browser.download.start_downloads_in_tmp_dir to true so the files I just open and don't want to permanently download don't clutter my $HOME/Hämtningar (downloads) folder. I tried to first prevent that by selecting the default action to do when tasked to open a PDF, but that didn't fix it, so I set the about:config flag. Unfortunately, setting the default action stopped Firefox from opening a PDF inline without downloading it and I cannot find any option along the lines of "Preview in Firefox" (as described in this support article ).

I view a lot of pdf documents via firefox, the light gray background makes my eyes and head hurt after prolonged usage. In the past I found a solution on this forum that advised to set pdfjs.viewerCssTheme to "2" in about:config. This set the background of pdf viewer to black/dark gray. This has worked for years until recently when the pdf viewer switched to light mode again (pic 1). I checked the about:config settings for pdfjs.viewerCssTheme but there appears to be no change. I tried restarting the browser, setting the theme to 0 and to 2 again, updating browser. Sadly the theme is still light gray. Is there a way to change it again? The desired outcome is in pic 2. I do NOT want to change the color of the pdf pages themselves.

Hi! After recently following the upgrade path from FF v52 to the most recent FF version, I find that logins in logins.json did not carry over with the upgrade. Out of 555 logins, only 44 appear. (I suspect these may have been imported from Chrome, since FF also imported my Chrome bookmarks without acknowledgment.) I see that the old logins are still in logins.json, and logins.json appears to be valid JSON when opening with FF.

I tried ensuring that logins.json, key3.db, and key4.db had matching timestamps, but that didn't correct the problem. I tried replacing key3.db and logins.json with copies from a backup of the v52 profile (it has no key4.db--is key3.db no longer used?), but then zero logins appeared (why I think the ones that do appear may originate with Chrome). I tried exporting logins to CSV, but it only captured those 44. I can see the logins are in logins.json, but the passwords are hashed/obscured.

I have profile backups, but I don't find a way to import the logins. (If I had to make a wild guess, I'd say the upgrade might have ignored my key3.db that paired with my logins.json, and created a new key4.db full of Chrome logins instead.)

How might I recover my logins from either the in-use logins.json or from my profile backup?

Thank you!

Fore some reason I am no longer able to open support.netapp.com in Firefox Getting a time-out error >> The connection has timed out >> The server at support.netapp.com is taking too long to respond.

This seems to have started after a Firefox update earlier this year, but I don't remember with which version it started.

I have already tried to refresh Firefox, un- and install Firefox

  (including deleting various entries in "%Programdata% and %appdata%
  and registry HKEY_CURRENT_USER>>SOFTWARE. Delete the entry named "Mozilla".
                     HKEY_LOCAL_MACHINE>>SOFTWARE. Delete the entries "Mozilla" and "mozilla.org".
                      HKEY_LOCAL_MACHINE>>SOFTWARE>>WOW6432Node.
                              Delete the entries "Mozilla" and "MozillaPlugins".

With no luck

This issue does not happen on any other browser (Chrome, Edge, Vivaldi) I have tried. But what I noticed on these is that support.netapp.com is automatically being redirected to https://mysupport.netapp.com/site This redirect does not happen in FF

If I enter mysupport.netapp.com manually it opens perfectly

So for folks who hand wrote thousands of lines of Actionscript code for Adobe Flash, it is incredibly upsetting and frustrating that a witch hunt went after Flash which we believe was part of a tactic by google to ensure its ads cannot as easily be blocked. Specifically google used all this "modern web" nonsense to become the monopolistic browser in place of internet explorer and to use that "power" explicitly to bend the future web to their will.

This is so upsetting, there are not words to describe it. And the fact that the "answer" is that folks who spent years and thousands of lines of code for Flash, now "simply need to completely re code everything from scratch in a new language" is offensive beyond recognition.

Please consider removing this "standard" response language or at least acknowledge the awful burden that was placed on folks by the decision to join the rest to remove the most popular web technology that helped build the internet, because google must serve everyone ads. It is just gross.

Honestly, we thought Firefox would defy the witch hunt and keep flash working to differentiate and look after the poor developers who suffered from this terrible, terrible action.

p.s. on the day Flash was officially killed off, chrome had more active "severe" security vulnerabilities than Flash. Thus, chrome is objectively less secure than Flash. I wonder how much google spent on paying news companies to post stuff about how "insecure" flash is and the stupid "modern web." I wonder if said "news" companies checked the claims, or just took the payment and posted their "sponsored content."

I am trying to sign into my bank accounts per usual this week and am encountering the above issue. I feel like I have tried everything. I can sign into the account on Safari, Microsoft Edge, or the on phone app just fine. I did not have this issue last week. To date I have tried: 1. Clearing cookies and cache 2. Forgetting the website 3. Turning off all addons/plugins 4. Changing theme 5. Uninstalling and reinstalling FireFox 6. Refreshing FireFox 7. Turning off fingerprinting 8. I do not use a VPN 9. Tried using incognito mode 10. Tried using safe mode

Please help. This is so frustrating. It is not on the bank's end as others can sign into their account just fine from Mozilla Firefox. It is not a computer issue, because I cannot sign in on either my laptop or my computer. I do have my browsers synced across machines, but I have tried logging out and signing in again to no avail.

Hello,

I recently purchased a VPN for my laptop. I bought a designated IP address set to Toronto, Canada. However, Firefox shows my location in Japan.

In my communications with VPN server they believe since whatsmyipaddress shows me where my VPN says it should, but FF shows me in Japan, the problem may be a leak at your end. When I created this account today and set my country to Canada (as suggested by PIA), closed everything and rebooted my computer I had hoped to see Canada (en) when I began a search. However, it still shows Japan.

I value my privacy on all devices and turning off location is the first thing I do. I'm now wondering if FF is getting this location from Windows.

Any assistance is most appreciated. Thank you,

Just recently, within the last two weeks (today is 12/22/23) Firefox it taking a long time to start. Firefox version is 121.0 (64 Bit) Windows 11 Home Ver: 22H2, OS Build 22621.2861 This is a reasonably new Acer Nitro PC (August 2023) with a solid state drive.

When I double click the Firefox Icon a large white box opens on my PC and remains that way for 10-15 seconds, then the white box fills-in with the Firefox screen. Once opened, Firefox works perfectly.

I tried the troubleshooter and Firefox starts instantly, as it did previously. I have no Extensions, Themes, or Plugins. I even disabled: OpenH264 Video Codec and Widevine Content Decryption Module. I tried Google and DuckDuck as the Search engine with no difference.

Any suggestions?

Thanks for your help.

I updated FF build from 120.0.1 to 121.0, then sound disappeared from all websites!!! and I checked my laptop the sound is working in other apps! now I watch YouTube like Charlie Chaplin. This issue happens in a new profile, as I created another one to see if it's a profile related problem, Thank you.

I have freshly install Manjaro system. On there I installed the Flatpak of Firefox. When I try to login into my Mozilla account for sync it doesn't load. See the screenshot. On my other computer it works without an issue. What can I try?

After updating to version 121, the cursor theme, while having it on the window, changes from the default one (Breeze) to Adwaita while also getting like 2x bigger. How do I change it back to default theme and size?

Hi, least night I was using Firefox and all was fine. I closed it as usual. This morning all of my tabs were gone! I still have my bookmarks but the tabs are gone. Is there any way to get them back? I can only assume that this is from the recent update?

Thanks, Steve

I have Windows 10 Pro 22H2 19045.3803. I am running two monitors. When I have many Firefox browsers open on both screens, reboot and restore previous session, the browsers all open in what ever monitor the initial browser was opened on. I haven't tried it with other browsers. All other applications open in whichever monitor they were in on reboot.
