Firefox Community Forum

I can't find how to have the icon for my OneTab add-on showing in the toolbar, like in the directions for how to use it. I just upgraded the OS on my laptop to Kubuntu 26.04, and when I synced my Firefox account to this new system it opened to the OneTab page where I was prompted to set up this app which was installed but hadn't been used.

Hello. I am back again with the same issue that I presented on the forum post three months ago. https://support.mozilla.org/en-US/questions/1594903?utm_campaign=questions-reply The difference is now it is happening on Firefox v157.0.1;everything else is identical. Qubes os R4.3.2 with Firefox 157.0.1 in a Fedora 44 xfce VM. To recap I open one window for Proxmox Datacenter Manager and as soon as I click to sign in Firefox completely disappears. I can open this in Chromium browser and Firefox ESR v.140.17.0 esr perfectly fine. Please consult the original post for all I did to troubleshoot this. I am working with the esr version now but would like to help put this issue to bed. Community members stepped up last time to help me so I am here to do my small part for others. Ask for any info you need and I'll reply ASAP. Thanks in advance. SDS

It bypasses my DNS when I turn it on and I don't want that to happen. I want this PC to never be able to turn it on again. That probably isn't possible, but I gotta ask. In the meantime: how do I use LinuxMint's firewall to ban the usage of the VPN?

Also: can the firefox devs make that an option? To have the option to never turn it on again?

As soon as I signed into the browser to sync my account, this issue began. I have deleted profile locks, started new profiles, opened in troubleshooting mode, fully reinstalled, and the issue continued (even before signing back in). I am out of troubleshooting steps and would like to avoid blowing my VM away if at all possible. Someone please help!

Hi there,

Since i have changed my primary email (the last primary became the secondary) i can't no more sign-in to "firefox relay" or "paid subscription" from my account. So I'm correctly logged in https://accounts.firefox.com/ but from there i can't connect to others services. I have this message :

Menu: Third-Party Login Failure An error occurred while attempting to login via your third-party account.

It a little bi annoying when you have paid subscription...

Thank you for your help.

Mozilla firefox debian package 157.0.1

When viewing a PDF in Firefox the URL bar indicates the file was downloaded to a temporary folder. If I then select "Save" from the PDF toolbar; or if I right click and select "Save page as" it opens a save dialog to the location I previously saved the same category of PDF to. For example I have separate folders for invoices, if the PDF is my electricity invoice it somehow knows and opens the electricity folder. If it is a water invoice, it automatically opens the water folder.

Whilst this is indeed quite handy, I do not understand how Firefox is doing this; nor do I understand whether this may be a privacy risk in some circumstances and should therefore be configurable.

Which dictionary are we using? (Or are we allowing English spelling to be supplanted with American or other spelling?)

Whereas in MS Windows I can choose UK English or one of the many different forms of English in use elsewhere, I'm noting that in Mozilla/Firefox I get the typical warning under a spelling that does not equate with the spelling used in the current dictionary and yet these spellings are not UK English...

Even I choose UK English as my default dictionary the spelling of "colour", "neighbour", aluminium, still give this indicator.

Is there a setting I may change to allow the tab icons / text to fully display down into the blank space that shows on my tab bar? I will attach an image. Thank you.

in the new nova settings ui the selected category is highlighted in light purple. not a fan. how do i change it. don't mind collateral damage as I'm not of fan of this color

Hello everyone.

Firefox updated today. I don't know—maybe some people like the new design of the tabs, the buttons in the drop-down menus, and the gradient borders around the active tab and the tab bar itself. But I’d like to revert to the old interface. How can I do that?

Thanks!

There's three images on the page, in FF only the top one shows, but if I hit refresh, all three show, but only for half a second, then they wink out. All three show in Chromium just fine.

Hey

I'm genuinely curious about Firefox BTS in this scenario.

Example: I open website (http://homedevice:1000) and it requires me to log in. Then I log in at (http://192*:1000) and it requires me to login. "homedevice" is a domain name for 192*, yet I still have to log in twice for the same IP under the same port. Why is it treated seperately the homedevice:1000 and the 192.*:1000 address?

so i used the web app from the firefox nightly adn when installed yt from it , the icon from it was very blurry which appeared on the taskbar , any fix for it , i have also added a comparison image from the brave which is on the left and firefox nightly 159 on the right

I have a list of websites that I keep in the cookies exceptions list so I remained logged in. But I noticed the list is blank in a few recent Firefox versions, even though the sites still retain the cookies. That means I cannot edit the entries or even see them.

Please forgive me if this question was already answered and that I might have accidentally overlooked that answer.

I'm running Firefox 144.0 (64-bit) under Debian 13 (linux).

I want to configure Firefox to never restore any previous session when it starts up, irrespective of how Firefox was last exited.

Even if a running Firefox session was externally killed via some sort of system command or because of a reboot, I never, never, never, never, never, never, never, NEVER (!!!) want it to restart in any previous session.

I ALWAYS (!!!) want Firefox to launch with its default start page, no matter what.

I tried all of the suggestions that I have found on line about how this might be accomplished, but with each one of them, there are cases where the previous session was restored.

I repeat, I do NOT (!!!) EVER (!!!) want the previous session to be restored, under any circumstances.

Is there a way to accomplish this?

Thank you in advance for any suggestions, and again, please accept my apology if this has been answered and I overlooked that answer.

I am using Firefox on Linux Ubuntu 26.04. I normally work with multiple tabs. Then I quit Firefox with all tabs open at the point of quitting. Some times on the rare occasion there can be a forced quit due to some issues. In my settings I have configured it not to open the previous tabs. In fact I want a blank page. But whenever I reopen Firefox, it opens those tabs and tries to reload which is annoying. Some of these pages take a long time to reload, and why would I want to look at tabs which I already have read. Or if it crashes due to some website on a tab why reopen something that crashed in the place ? Can you fix this. Thanks.

My Dell Precision Laptop from 2019 runs a frequently updated Ubuntu 24.04. About one or two weeks ago, after one of the latest Firefox updates, i noticed that video streaming produces rectangular flickering in rapid sweeps. ( Also fast scrolling large text websites produces similar flickering, I think I would have noticed it before...) . If you detected it once, you see it always again... :-( First I fiddled around with the nvidia settings because the driver was also recently updated, without much success. Playing locally stored videos, e.g. with VLC media player, still works fine, so the nvidia driver is not the problem i think. Yesterday I installed Chromium and the video performance is fine! As good as with firefox some weeks ago! So it must be one of the latest updates, that causes the problem. Generally I like firefox more than chromium. I like the control you have, e.g. via Add ons.. So I hope that the firefox performance will increase again... Thank you for firefox! Florian Mengedoht
