Firefox Community Forum

I updated my desktop browser today and now there is an expandable sidebar at the left margin of the window showing tool icons for Tabs from other devices, History and Customize sidebar. I can see how to remove tool icons and how to expand or collapse sidebar but can I remove the sidebar completely? Is this an option? I prefer the old look with the browser web page content extending all the way to the left of the screen, without the narrow vertical sidebar.

When I installed Firefox, I struggled to find a theme that was easy for me to see. So many had dark borders/backgrounds or busy backgrounds or transparent. It appears that I'm using the default at present and am happy with everything but the visibility of those little icons. Is there is a way to make them darker? Thanks

Since the recent update to Firefox 131, I can no longer use the Billpay option of my TD Bank account. I am able to log into my account without any problems and use all of the options except for Billpay. I want to add that I know I am not alone with this problem as I have seen several others with the same problem but with different banks. It is the Billpay option which no longer works.

As I said, the bank site is fine until I click on "Billpay", Then I get this: begin quote: "Why can't I access Bill Pay?

I have disabled uBlock Origin, Enhanced Tracking, tried Private Mode, Troubleshooting Mode to no avail.

I have also cleared cookies & data. This appears specific to v131. Any suggestions??

I currently use firefox 133 (32 bit) on Windows 11. Every time my router resets (either due to power outage or xfinity server outage) firefox fails to connect to multiple websites after internet service resumes, for example, I cant get to twitter.com (x.com) or even the mozilla support page while on firefox. Screenshots of the error and associated stuff are in the attachments. Firefox currently can't even check for updates.

All the webpages that do not work firefox due to the issues highlighted in the screenshots load perfectly fine in other browsers like chrome and edge. These issues in firefox go away after a couple days without any intervention which I explains how I was able to use firefox for these webpages prior to my last network outage and have still not been able to solve this post network-outage issue.

Things I have tried so far: - Disabling proxy in firefox: Did not work so I re-enabled it since that is how it was before the issues happened. - Re-install firefox 133: Downloaded an installer from chrome to do this but this also did not fix the issue. Note that I first downloaded the mini installer which downloads files as part of the installation and that also failed to connect to mozilla. So I downloaded the full installer. - Cleared cookies and data: did not work - DNS over HTTPS: Swicthed it off, did it did not work, so I switched back to the default setting. - Logged in to the router from firefox using the router's IP address: Not sure why I thought this would work but it did not.

Any help would be appreciated to solve this issue once and for all.

The other day I accidentally pressed a keystroke that changed a Firefox setting, and now it thinks I'm on a mobile device/displays sites in mobile view where possible by default. This has persisted despite restarts of the browser and the computer and has been happening since Sunday (Australian time). I've tried opening the Responsive Design dev tool and I've sent screenshots to a techsavvy friend (I'm totally blind and use a screen-reader, so couldn't tell this was happening until I tried to use a site that had a radically different layout in mobile view), and aside from not seeing an exit button or a switch to change device mode, he couldn't tell what was going on.

I'm stuck and need help! I would like to unmobile my Firefox!

I prefer the tabs be below the bookmark bar, and successfully modified the CSS file to do this some time back. Now update 133 has once again pushed them up below the menu bar. What do I have to do to get them back where I want them this time? And why can't you just leave the tab location preference alone when doing updates?

Since updating Firefox I can no longer connect to known good sites without getting "Did Not Connect: Potential Security Issue".

This includes U.S. government sites! For instance, try connecting to https://covidtests.gov/ .

Why completely block access to the site? Why can't I make exceptions or tell Firefox to accept the risk and continue?

Several weeks ago, I was attempting to upgrade from Windows 10 to Windows 11. In the process, I deleted Firefox (using Revo Uninstaller) and then reinstalled it, downloading it from the Mozilla website. Unfortunately, it didn’t run, giving me, at different attempts, different error messages. In the time since then, I have read many suggestions from many different websites and I have tried some of these suggestions, all with no success – until today. I have just completed the suggestions made on https://support.mozilla.org/en-US/questions/1327628 and Firefox is now back, working. I am happy and grateful, but not finished. None of my personal data came with the currently functioning version of Firefox. Since the re-emergence of Firefox, I have been reading several websites dealing with copy, backup and restore of my Firefox profile. Right now, the path C:\Users\rsuth\AppData\Roaming\Mozilla\Firefox\Profiles\ shows 5 folders: Two of the folders show 11/11/24 as the date modified (probably the date of the download from Mozilla). The folder 0dppjrfa.default contains one file, times.json, dated 8/11/2020. The other folder, ru82tlj5.default-release, has 97 items, most dated 11/11/2024. The remaining three folders are all dated 12/2/24 (today, as I write this). One folder’s name ends .default, the second name ends .default-release, and the third name ends .default-release-thirteen digits. The question that I am asking here is what do I do next to, hopefully, bring back the personal date I had with Firefox before my updating to Windows 11. Should I delete the folders dated 12/2/24? What, if anything, is the significance of the folder whose name ends in 13 digits? I’m hoping someone will be able to tell me how to fix these Firefox problems. And if I can, then I hope to be able to do something similar to help me bring back Thunderbird as well. Thunderbird became unfunctioning at the same time as Firefox. Thank you.

I updated to version 133 today and was confronted with the vertical tab bar. I did not ask for this or want it, and now I can't get rid of the side bar, in fact I seem to have just made it worse / wider. How can I get rid of this (and block it) It is just taling up space on my screen. Please help.

I haven't upgraded browser versions for a while and I'm now going from 109 to 132. Pretty bad I know.

I'm having a number of issues but for this post I'd like to concentrate on userChrome.css.

In version 109, I had a custom font for the top menu bar, the top menus, the bookmark toolbar, the bookmark toolbar menus, and the right click menus. I did this by including the following in userChrome.css (as per [https://support.mozilla.org/si/questi.../1335097|here]:

1. navigator-toolbox { font-family:"MyFont" !important }

This worked great, but it is no longer working in version 132. Obviously I don't know in which Firefox version this stopped working.

Has this been disabled by Mozilla or has it been changed? If it's been changed, how can I achieve it now?

I'm very grateful for any help!

I am writing to request assistance with my Mozilla account. I am unable to access my account due to several reasons: I have lost access to the two-factor authentication app, I have lost the backup data with the 10-digit recovery key, and I no longer have any devices where I was previously logged in. I only have access to my email address.

I do not need access to the synchronized data; it would be acceptable if you delete it and allow me to register a new Mozilla account with my existing email address. Using a different email address is not an option for me.

I am in the process of transitioning away from the Google ecosystem and would like to use Mozilla's services and products. Could you please help me reset my Mozilla account so that I can register a new one with my current email address?

Thank you for your prompt attention to this matter.

Best regards, Evgeny

I'm having much difficulty in attaching a article I see to Facebook. Its possible the problem may be I'm not using the right instruction on the Firefox options when I right click the article I want to attach to Facebook. Some of those options are, Save link as, Copy link, when I right click for options. Can someone explain what is the right option to use? And, how do I proceed once I choose the correct option to make that attachment to a Facebook message I'm replying to? There are times a picture of the article will attach to the Facebook message, but the text that is associated with the attachment will not appear? Can someone please help? Thank you.

Since the 132.02 certain eBay items will not display its shipping info. Only on Firefox. Its not addon because I disabled all and I have the same addons installed on edge and all good there, I can see the shipping info on edge. And its only about 50% of the items which is weird. I have done the basic troubleshooting and I have to think it was this update. If you see the images attached Shipping values should be displayed. Some have a $ value some say +shipping, those are not displaying the value. Please help me figure this out as I use Firefox ALL day but if this continues I HAVE to switch. Ebay is my main source of income now.

With reference to my question just posted, also now when I click on my Firefox browser, the Yahoo search engine seems to take over and it won't let me come out of it. Mark

I know that typically mozilla does not put a low bound on advisories, and https://www.mozilla.org/en-US/security/advisories/mfsa2024-40/ is the advisory for vulnerabilities fixed in ESR 128.2. CVE-2024-8387 is listed here. yet the advisory for 115, https://www.mozilla.org/en-US/security/advisories/mfsa2024-41/ does not list this vulnerability. Was this something that was only impacting 128 (for the ESR builds) or is there a mistake that either 115.15 did patch it but it wasn't documented, or the patch has been missed and ESR 115 is still vulnerable?

When I open up the Add-ons Manager it shows Window Titler is turned on. But Ctrl-Alt-T no longer works, there is no button showing for it, and it seems to be gone. A button for it does not appear in Customize Toolbar. It is the single most important reason I stay with Firefox. How do I get it to work again? Thoughts appreciated.

A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

• Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
• For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
• I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

Is it possible to bookmark a particular section of a page, whereas the bookmark will take you to that location?

Textmarker was suggested in another thread, but apparently it is no longer working.

Went into Firefox and got the error message: Platform version 131.03 is not compatible with min version>=131.02 & max version>=131.02 So I'm thinking that the last update caused the error. I did a system restore to a week earlier, and after 5 hours, the computer rebooted to that date. Upon opening Firefox, I found the the notice that the next time Firefox opens, it will update. After closing, and reopening, Firefox updated and displayed the same error message. Nor quite sure what to do, I downloaded Firefox again, and was going to uninstall and reinstall. But as soon as the download finished, it loaded. So now I have the new Firefox without all of my saved bookmarks and passwords. I thought I'd read someplace that that wouldn't happen, and all of my password and bookmark history would transfer to the new Firefox. As if that wasn't enough to ruin my day, I found that the new Firefox isn't working in my wife's account on the same computer. She gets the same error message as I did before the new install. I know, my fault for not backing up the bookmark and password files, but what's my option now?

I have a custom pitch black theme ( pls add it without addons ) which now only flashes for a second when i open the browser and returns to the normal greyish dark mode. When i go to Firefox Color addon page and load it again in saved themes it stays pitchblack even if i open another browser window until i close all the browser windows .
