My Browser keeps on telling me there is an update... I've updated, reinstalled the latest version and it still keeps giving a pop-up saying there is an update...

How do I get rid of these pop-ups???

I updated the iOS app today and it closed all my tabs in private browsing mode and will not keep any open. It also will not default to private browsing anymore even if I open a link from a private window. The help pages list settings that do not exist. Please advise

Sync collections after Android factory reset, have Firefox on desktop that is synced, but the new Android install synced bookmarks but not collections, of which i have many, or did.

I'm sure I've just missed a step, but been reading for 3 weeks now .... any idea's?

We're exploring adopting a default deny policy for Firefox extensions in our enterprise. However when I tested this by creating a custom policies.json Firefox unexpectedly removed all extensions for me, including the ones I thought I had allow listed. Here is my policies.json but just keeping in the Facebook Container add-on to illustrate:

{

   "policies": {
       "ExtensionSettings": {
           "*": {
               "blocked_install_message": "Only approved Firefox extensions can be installed, please email your request to itdept@example.org",
               "installation_mode": "blocked",
               "allowed_types": ["theme", "dictionary", "locale"]
           },
           "@contain-facebook.xpi": { "installation_mode": "allowed" }
       }
   }

}

What I would like is to to allow pre-approved extensions (including if they already are installed) and all other types of add-on, but remove and prohibit installation of unapproved extensions.

Can anyone assist, please?

Now that firefox Android supports addons, please someone make addons for History export..

Is there any other better way to export history.. I have tried sync.. but there seems to be some limitations in sync, it didn't sync all the history..

Recently the email composing function has ceased working in Thunderbird (ver 65.0b3 (32-bit)). Other functionality also recently changed ie clicking the get messages button no longer downloads new messages so we now have to select Get all new messages from the drop down arrow attached to that button. We are only able to type in the email body text area when replying to messages but not when we compose a new message from scratch. The compose new message screen allows us to put in send from and send to as well as type a subject line but doesn't allow us to click in the body text area. If I update the subject line and then tab to try and get to cursor to move to the body text area, all that happens is a dotted line border shows around the body text frame box. I have tried safe mode without addins and removed silverlight but nothing has changed. My wife said she accepted some update a few weeks ago but can't remember what it was for. I will attach a screen shot of the compose page to assist in helping resolve this issue. Thanks

i love 65 because it is SO much faster but i would like to be able to sync my calendar.

the older versions just do not work very well for me. too slow

thanks, scott

I'm having huge memory problems with Firefox. In about:performance I can see that the extensions process takes up way too much memory. When I start Firefox it usually shows a memory usage of around 180MB. However, at some point the memory usage of the extensions process starts to increase and it doesn't stop increasing until my RAM is full and then it increases even further. It increases until I restart Firefox or until it uses so much RAM that my computer runs incredibly slow.

Below you can see a screenshot of the Task Manager showing how much RAM is available on my computer and a screenshot of the about:performance page showing the memory usage of the Extensions process. The RAM available on my laptop is 10GB (the default configuration was 4GB of soldered RAM plus 4GB of exchangeable RAM. I have upgraded from 4+4GB to 4+8GB but 2GB of the soldered RAM on this laptop are used as GPU memory so the remaining RAM is 10GB). The about:performance screenshot shows a memory usage of 13GB for the extensions process which is possible because Windows automatically pages RAM on the SSD when I'm running low on available physical memory. This enables programs to actually use more memory than the available physical RAM but of course programs become incredibly slow when the RAM is full and huge parts of memory have to be paged on the SSD.

My actual question: How can I find the cause of these memory problems?

What I've tried so far

- I have created a memory report on about:memory. The result is at the bottom of this post. - I have watched the about:performance page and tried to find out what action triggers the memory usage of the extensions process to increase. At the start of the browsing session the memory usage is only at around 180MB. It stays like that for a while. At some point it starts to steadily increase by many GBs. But I couldn't find the cause. I don't know what triggers the extensions process to increase memory usage. - I could simply disable extensions and see if the problem gets solved. But I want to know which exact extension causes this problem. It is very difficult to find out which one it is because I have many extensions and I don't know what causes the memory usage to increase. So I would have to disable extensions one by one and wait for an indefinite amount of time and check whether memory usage stays low. But I don't know how long I have to wait until the memory usage would increase because I couldn't identify what triggers it to increase.

Rather than just using trial and error I would like to find a way to use debugging tools to exactly determine what causes the problem.

_______________________

This (https://pastebin.com/U3QXTAt9) is the memory report from about:memory. This contains the whole extension (pid 18332) section (copy & pasted by selecting the text on the about:memory page). I have left out the rest because I don't know if it contains private data. Please note: this is not taken from the same browsing session as the screenshot that shows a memory usage of 13GB. Why? Because programs run very slow when memory is low and large parts of memory are being paged. The debug tools usually require a lot of RAM and CPU performance so it's very difficult to use the debug tools when the memory is already full and programs are already running slow. This memory report shows a very high memory usage of the extensions process. In this case it's "only" 3.5GB but it was taken in an early stage of the increasing memory usage. As shown in the screenshot below, memory usage can go even higher than the available physical RAM on my computer. The memory report doesn't clearly show which extension is responsible for the high memory usage. In the memory report, I can only see a high memory usage for the items gc-buffers and gc-heap which leads me to think that the memory problem has something to do with the garbage collector. However, I cannot see which extension is responsible for this. No item in this list with a description that identifies a specific extension has a high memory usage. This is only an excerpt from the memory report (only the extension section). I went through the whole memory report with Ctrl + F "moz-extension" and looked for items with a high memory usage but I didn't find a single item with high memory usage that belongs to a specific extension.

I tried to use a ftp link setting firefox as the default ftp app, not realizing firefox no longer supports ftp. I am unable to reset the default app and can't find the setting to do so. I downloaded filezilla and wish to set it to be the default app for ftp. Can someone help me with this? Before anyone suggests it, resetting firefox to default settings is not an option.

After an update of both macOS (to macOS Sequoia 15.0.1) and Firefox Developer Edition (to 132.0b3 (aarch64)), the Bookmarks Toolbar stopped working. The same issue appeared on my Windows PC.

Bookmarks toolbar is visible, I can show and hide it but it does not display any of my saved bookmarks. Luckily, they were not deleted and I still can access them via Bookmarks Menu, which is less than optimal.

The Drag&Drop functionality does not work either. When I grab the opened Tab, drag it on the Toolbar and release it, the Tab gets opened in the new browser window and it's not saved.

Hi y'all, when I use firefox DE, there is a bug in which the search bar overlaps with the tabs, after the new release. Is this because I use a custom CSS that reverts the tabs back to the old style? I would really appreciate it if I could still use the old firefox tab style without having my search bar overlapping with the tabs

I am migrating to a new phone. WhatsApp offered firefox as an option for storing its passkey. That took me to the connection and synchronisation process which the new phone said had failed. However all my tabs and other passwords appear to be syncing. Now selecting firefox to store the WhatsApp passkey takes me back to the failure page every time. Any idea how to restart the passkey addition to firefox process? WhatsApp won't work whilst I'm hung up in limbo between the two apps.

As the title says, I got a problem with Android version of Firefox that sometimes on some webpages it just hangs and doesn't load the page at all. While it's hanging there if i try to open extension settings it doesn't even load that, just opens blank page. Only way around it is to close tab and try again later. Sometimes i can just close tab and on next try it works, sometimes it just doesn't. I've had same issue with PC version of Firefox and it seems to be fixed after disabling HTTPS over DNS. On Android I've tried changing network.trr.mode to 5 but with no luck. Also ive tried disabling extensions and changing some options but whatever I do it just still keeps happening. Btw its a new install after years of not using Firefox, perhaps because of the same issue.

Hello, I have a reproducible issue on Firefox Beta for Android on my POCO X6 Pro 5G running HyperOS / Android 15.

When tapping mailto: or tel: links in Firefox, nothing happens. No app opens and no chooser dialog is shown.

The same links work correctly in Google Chrome, so the Phone/Dialer and Email apps are properly registered with the system.

This appears to be related to Bug 1988946, but it also affects Android 15 on HyperOS.

---

Steps to reproduce

1. Open Firefox Beta on a POCO/Xiaomi device running HyperOS.

2. Visit any webpage containing a tel: or mailto: link.

3. Tap the link.

---

Actual Result

No action is triggered.

No Intent Resolver popup appears.

No dialer or email app is launched.

---

Expected Result

tel: links should open the default Phone app.

mailto: links should open the user’s email app.

If multiple apps are available, Android should show a chooser dialog.

Device Information

Device: POCO X6 Pro 5G

OS: HyperOS, Android 15

Firefox version: Firefox Beta 146.0b4

Build: #2016126791

GV: 146.0-20251117130030

AS: 146.0.1

Build date: 2025-11-17T13:00:30

What I have already tried

Enabled “Open links in apps” in Firefox

Reset Firefox default preferences

Reset Phone (Dialer) defaults

Granted all special permissions (background activity, pop-ups, etc.)

Tested Firefox Stable and Beta

Cleared app cache/data

Rebooted device

Verified that Chrome opens tel: and mailto: links correctly on the same device

---

Additional notes

In HyperOS settings (“Opening links”), Firefox does not receive supported link types.

The Phone app does not appear in “Opening links”, but it works fine with Chrome.

This suggests a compatibility issue between Firefox’s intent handling and Xiaomi/POCO HyperOS on Android 15.

---

Conclusion

This issue is reproducible 100% of the time and affects basic link handling functionality. I am available to provide logs or run additional tests if needed.

Thank you!

Why are basic features like editing bookmarks not in the app. On chrome you are able to click and hold on a bookmark to select it, then click and hold on it again to move it anywhere you'd like in the folder. Also there is no "move to" option on Firefox which would make sorting much easier, it would be nice to have such a simple feature like this for convenience.

I wanted to try thunderbird 60 (60.0b6). Fresh install with a new profil.

And I can't find the "quick reply" option (the quick reply field that allow to quick reply to an email, like in the regular version of thunderbird 52.8).

How do I turn that on ?

Thank you.
