I have installed the LastPass extension for Firefox, more than once, but the LastPass icon does not appear in my browser bar. It used to be there, but disappeared a few weeks ago. I have tried to reinstall the extension, but it has had no effect.

I have an iMac with Sonoma 14.3.1 with Firefox 115.9.1 esr . It is for personal use, not for a business. I just learned that there is another Firefox version (124.0.2) which is not esr....

Which version should I use and why?

If I should use the "normal" version, how do I replace the esr version with the "normal" one ?

Thanks.

For the past week, my browser does not auto-update. I have to download the update and re-download the browser.

I went into the settings and found the update section and when I clicked "Check for Updates", it kept saying "failed to check for updates". I tried with my proxy-settings on with VPN on, proxy-settings on with VPN off, proxy-settings off with VPN on, proxy-settings on, with VPN off.

This is in my personal laptop, where I am the only and admin profile.

My Firefox used to to auto-update but now it keeps saying I need to download the update, but my browser can't even tell if I have the most current version or not.

Hello, I use Ufile for my taxes. They weren't bad a few years back. For the past 3-4 years they have been a problem with their website not loading properly. They want you to use Chrome (as do more then a few websites). I don't like Chrome for privacy reasons. What do you suggest I do? Load Chrome for Ufile and then delete it. Can you suggest a tax website that works better with Fire Fox? Open to suggestions. Thanks in advance. Bob

The AccuWeather part of the Firefox homepage says I'm in Portland, Oregon, USA, but I'm not even in the same country. I tried to change it according to the directions I found earlier, but the only drop-down for my city was another city in the US but none in any other countries. So now I can't change my location. How do I change my location? It wasn't like this yesterday and I have no memory as to how it became "Portland, Oregon" since last night. I don't even have a VPN so it isn't that. How do I change it back to my area without using my exact location?

My bookmarks have all disappeared, and while I have tried to follow the instructions on the help page to restore them, nothing is working as it has been indicated that it should in the help instructions. I do still have my Bookmarks tab on my tool bar. When I click on it I get a pull down menu, which does have a Manage BookMarks bar. However it is not at the bottom of my pull down menu, but at the top. When I click on the Manage BookMarks bar, instead of getting an Import and Backup Button, my pull down menu disappears, so I can not select Restore to use to get dated backups.

In the same way, I can not create new Bookmarks. When I click on Bookmark Current Tab, instead of getting the white box to enter instructions, the pull down menu disappears, just as it does when I click on Manage Bookmarks. I have never had this problem with Firefox before in all the years I have used it. I have no idea what has happened.

For some days now the Guardian (UK journal) website can't be loaded. It's specific for Guardian, I have no such problems with other sites, and I don't have this problem with Guardian with Chrome. I've erased cookies and caches, restarted my computer, to no avail. I'm using version 146.6.0 of Firefox on MacBook Pro 2020 with Sequoia 15.7.1.

When I listen to music via Firefox, my computer goes into sleep mode after 15 minutes (windows close and password is required)^)^. I've looked everywhere to find a solution to this problem, but I can't find one... Can you help me?

I received an email from breach-alerts@mozilla.com informing me that Mozilla Monitor⁩ discovered a data breach that includes my personal information: Unfortunately, I don't know if this is a legitimate email from Mozilla. Can anyone confirm if it is or is not?

Thanks

I have been using 1Password 7 to manage my login credentials. It includes a Firefox extension to fill in account names and passwords in login alerts and pages.

Firefox 147.0.1 (macOS aarch64) in January 2026 has broken 1Password 7's ability to fill in account names and passwords.

To reproduce: 1. Install 1Password 7 Version 7.9.11 (70911000) and its extension version 4.7.5.90 in Firefox 147.0.1 on macOS. 2. Visit a URL for which 1Password 7 has login credentials. 3. Click on the toolbar icon for 1Password 7. A 1Password 7 dialogue box pops down from the icon, containing the username and password for that URL. 4. Click the Autofill button in that dialogue box.

Observed behaviour: 1. Username and Password fields remain blank.

Expected behaviour: 1. Username and Password from 1Password 7 appear in the Username and Password fields.

For approximately the last three months, there was a partial failure similar to this. 1. 1Password 7 popdown dialogue moves from the toolbar icon to the Firefox tab for that URL. 2. Username and Password fields remain blank. 3. Workaround: click in the username field, then tab 2-4 times to further UI objects in the login credentials form. Then click the 1Password toolbar icon, then click the Autofill button in the popdown dialogue. Then, the Username and Password from 1Password 7 appear in the Username and Password fields.

The expected behaviour occurs for the same URLs in Safari.

Thus I suspect that Firefox has somehow changed its behaviour in the last few months to cause this regression. I have not changed the 1Password software versions in this time, because I am intentionally using a previous version of 1Password.

I am looking for a fix or workaround which works with my current 1Password software version. I am not interested in a solution which requires me to upgrade to the current version of 1Password. (The current version of 1Password imposes a feature which I am resisting.) I realise that this reduces the chance that I can persuade the Firefox team to find and correct this regression.

I returned a phone that I had for 2 weeks (the phone was a Motorola G Stylus 2024, if that's even relevant), and while I did a factory reset on the phone before returning it, I am worried that my Firefox account information is still accessible through the device.

One reason why I am worried is because, when looking at synced windows open, *everything* that I had open on there was open and accessible through my account. Another reason that I am worried is because I did not log out on the device before returning it to my local Best Buy.

It'd probably be impossible to track down the exact phone that I had, but can anything be done? Should I redo my log-in password for Firefox (or even all the sites that I used on that phone) or am I worried over nothing?

It has been observed that when a user uses the Firefox browser and tries to download a DDD file, the file format is .pdf instead of .ddd. In the devtools, it was observed that the content-type is text/plain in the response to the request. I changed the content-type to application/octet-stream, but the error still persists

Firefox claims does NOT save site/URL visit information while in Private Mode. And I thought that was true. However, I just discovered that Firefox DOES SAVE Private Mode URL/Site visits - in this specific place. I don't know how long the history will be saved - it looks like at least as long as the Window is open. I want to keep most of my open Private Tabs open - but want to Delete/Clear the ones I'm done with. I thought/understood that Private window/tab/visit info was not tracked/saved - and it's not saved in History, or Searchable. But it appears that this doesn't apply to the Recently Closed Tabs MenuItem. And there seems to be NO 'delete' or 'clear' option for this field. I can't find any reference to the subject in the Forum or Articles. The picture I've attached is NOT of the Recently Closed Tabs while in Private Browsing, but is the same MenuItem and field contents. Thanks for your interest. I'm hoping someone can help me figure out how to delete/clear this specific history.

This current version of Firefox (126.0) is preventing Yahoo! Comments from showing/displaying in ANY Yahoo! article. After I finished reading a Yahoo! article, the Yahoo! Comments is viewed but upon clicking on Comments, it just disappeared. It happens in any Yahoo! article with Comments. I used Safari to see if I experience similar issue but Safari is able to show/display Yahoo! Comments upon clicking on them. I have no other browser plug-in or app in Firefox preventing Yahoo! Comments from showing, it seems to be a Firefox JavaScript issue.

I have uninstalled Adobe Acrobat from my Mac Mini running Sequoia OS. Acrobat is not listed in my Firefox extensions. Yet, when I open a PDF from a link in an email, it opens in Acrobat (clearly announced as such with its logo) in a Firefox tab. Also, I have my Firefox setting for PDF files set to "Open in Firefox".

Acrobat is a vicious plague on my life, and I want it gone. Please assist me in ridding it from my Firefox use.

Thank you, Tom

Hello Firefox Community,

I'm experiencing a significant issue with my Firefox bookmarks after migrating to a new Mac device. Background:

1. 1 I recently switched to a new Mac and installed Firefox.
2. 2 Before the switch, I was using Firefox on another Mac, and I had synced all my bookmarks and other data with my Firefox account.
3. 4 The old Mac has since been formatted, and unfortunately, I no longer have access to it.
4. 5 After signing in to my Firefox account on the new Mac, I noticed that none of my previously synced bookmarks appeared. It’s as if the sync didn’t bring over any of my old data.

TL;DR: Despite having synced my bookmarks with Firefox on my old Mac, they did not transfer to my new Mac after syncing. I’m worried that these bookmarks might be lost forever.

Is there any way to recover my old bookmarks from the Firefox Sync servers or through any other means?

Thank you in advance for your help!
