When i scroll up and down on a page, it instead provides the back-page instead of scrolling up and down on the website. this is for all websites. the scroll function works oroperly in system settings, it is only with firefox. autoscrolling is enabled in settings.

Installed Firefox 122 in a new Windows 10 installation and added some extensions (e.g. Gesturefly, Update Scanner, uBlock Origin, Uppity). These pinned fine on my old installation. But I cannot find how to pin them on the new.

All the help I have found Googling, or using search here, says go to the Add-ons Manager page and right-click the extension and use "pin to toolbar". Alternatively click the extension and click the gear icon and use "pin to toolbar". But when I right-click there is no pin to toolbar context menu entry. If I left-click the gear I get "Check for Updates, View Recent Updates, Install Add-on From File, Debug Add-ons, Update Add-ons Automatically, Reset All Add-ons to Update Automatically, Manage Extension Shortcuts". If I right-click the gear I get a line of icons (left, right, reload, star) followed by "Open Image in New Tab, Copy Image Link, Email Image, Save Page As, Select All, View Pate Source, Inspect Accessibility Properties, Inspect (Q)". If I right-click the extension in the Add-ons Manager page itself, I get a very similar list. In no case is there a pin to toolbar option.

How do I pin an extension, given the above? What have I messed up?

Dear Firefox support community

Greetings from southern Germany, near Lake Constance :-)

I have issues since a few months that Firefox loads website only when I actively click on the app and put in foreground. Then the tabs start loading. Why is that?

After startup of Windows 10, I usually run a little batch script of mine starting various applications such as Outlook, Notepad++ etc, including Firefox along with my favourite websites, just like this:

start "" "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Firefox.lnk" https://de.wikipedia.org https://www.google.de [and more...]

So Firefox loads and opens all the tabs in the background, while other apps such as Outlook or Notepad++ come in the foreground. I read mails etc. before I decide to check e.g. Wikipedia. So it might take 5 minutes after Firefox got opened before I actively put it in the foreground. THEN I see no websites got loaded, and THEN Firefox starts to load the websites, which then takes the normal amount of time of a few seconds.

I wonder why Firefox does not load all my requested websites directly after start in the background.

An annoying side effect is, when still in Outlook and clicking on a website link in an email, it won't open in Firefox, most likely due to that reason that Firefox still waits for all the other websites to load. I need to put it into foreground, wait for the loading process to complete, and then go back to the email and click on the link again.

Any ideas would be greatly appreciated!

Many thanks in advance for your assistance & Best regards Volker

I have a Blackview Tab16 (10" screen), which I bought last year; it was running Firefox quite happily until a couple of months ago. Now when I click on the icon, I get a sort of 'welcome' screen (with some message about a search widget?) for a fraction of a second, then FF closes and I get an error message saying 'Sorry. Firefox had a problem and crashed.' The version of FF is 126.0. I was told to try clearing the cache, but there is nothing there to clear! The tablet is running Android 12 / DoKe OS V3.0.

I have an 8" Blackview tablet which - despite needing to be plugged in to run all the time! - opens & runs Firefox perfectly happily. It's my main browser on my MacBook as well, and will run on my iPhone.

The email address that I have used ever since email began has been [edited] @qis.net. Unfortunately, the inbox storage space on Quantum Internet Service (QIS) is only 1GB. I use Thunderbird for emails (recommended by QIS). The account with QIS is an IMAP account.

Yesterday at 4:40pm my inbox became full even though I have moved a bunch of the emails with larger attachments to offline folders within Thunderbird. That's when the nightmare started. No incoming emails can get delivered at this time. Have been in contact with QIS (I personally know everyone there including the owners. They're good people) It seems that we do not have a way to get into the inbox and remove files from their server (s).

After working all night trying to sole this mess, I have set up a new email address to maintain a form of communications on a major engineering project.

The new email address for me should be changed to : [edited] @gmail.com

Please make this change at Firefox. When I try to login on Firefox, it sends a code to the old, non-usable email address. Since the inbox at QIS is full, I can't read it to get the code to respond. If the code can be sent SMS to my cell phone, that would be fine. [removed phone# from public support forum] is the number to use.

I hope all this makes some sense at your end. I am not a guru with this stuff and a very dear friend of mine who was an "IT guru", as I called him, has passed away about 1 year ago.

I appreciate any help you give.

Hi, I've recently downloaded firefox and trying to add extensions that were similar to the ones I used on chrome. My problem is that all the extensions (Hoverzoom, Short Keys) in the extensions tab in the toolbar and appear to not be working (both in private and normal browsing). However the extensions (Ublock, SponsorBlock) that have their own icon on the toolbar seem to be working fine.

I've attached a reference image,

Any help would be greatly appreciated.

My samsung galaxy S5 neo android smartphone 16gb. Is not compatible a enough for me to browse on some of the website links, also is not compatible a enough to download some of the apps on google play store. So that's the reason why i downloaded the mozilla fire fox app for the first place. Thanks a lot I really do appreciate it . Yours Sincerely Rees Ossai

I am using Samsung S23 with the latest One UI and Android 14. Samsung's built-in browser has a neat feature where you can open YouTube or Reddit links in the apps installed on the device instead of viewing them in the mobile version of the website in the browser. I assume that Firefox has the same functionality called "Open links in apps" in the settings, but I tried all the available options and neither YouTube or Reddit links are automatically opened in their respective apps, nor is there a button anywhere to force them to open in the apps. Am I doing or assuming something wrong, or is this a bug?

I have installed firefox in my laptop for years. after latest update, firefox runs just fine only for the 1st time, then after closing the app / restarting the laptop, firefox keep giving error (attached) I have tried to refresh, run troubleshoot mode, uninstall and reinstall again at one point I was able to recreate the issue only after reinstalling firefox 126.0.1 portable version and then syncing to the profile ( run ok for 1st time, then it broke down after closing it) The problem also seems repeatable using firefox 115 protable Now, I tried to reinstall the portable version from scratch, it keeps hitting same error from 1st run

I have also double check the firewall and antivirus to make its not blocking All other browsers works just fine

Out of nowhere, the browser stopped when I was browsing and the pages started showing slowness. 👇🏻👇🏻👇🏻

I'm so annoyed by these notifications for utterly random websites / "news" that started after a recent update (see attached screenshot). I don't want these, bit also don't want to turn off notifications altogether. Thank you!

I just lost several hundred tabs on Firefox mobile right after it updated itself. The most recent tabs show only ten of those tabs, which were all opened and closed today and aren't part of what I need to restore.

How do I get my tabs back? I've seen no 'restore previous session' option. My laptop only shows the few I have open now. What do I do to restore them?

I changed the 'mousewheel.with_shift.action' to a '5' in 'about:config' to be able to use pinch zoom on my desktop with a keyboard and mouse, like I'm able to do on my phone or laptop with a touch screen. This does work properly and I'm able to pinch zoom by holding down the Shift key and scrolling my mouse wheel up and down.

However, there is an issue of sensitivity. The pinch zoom is painfully slow, and I have been unable to adjust its speed. If there exists an option to change the pinch zoom sensitivity, I'd greatly appreciate the help.

Hi,

I'm on a Pixel 7 and I use Firefox Focus as my default browser app for news/socials/daily browsing. It's not connected to any Google accounts and I erase as I go along to avoid cookies/marketing/ad tracking. I also run Bitdefender. Focus background data usage is off.

Today I ran out of mobile data and on checking apparently Firefox Focus used 9GB of foreground data just today. I'm not sure how, as I was only on mobile data for about an hour, and the phone was in my pocket for that time. It shows 11 minutes of screen time, but 49% of my battery used today.

Is this a bug, or have I been hacked/compromised?

Cheers

After update to 126.0.1 I cant access two of the four windows that are open. They are still listed under the Window toolbar option but clicking on them reveals nothing, as if hidden except they are not in the Mac toolbar. Not sure if this is a new feature or glitch, any help would be great, the two windows I can't currently access contain alot of tabs I need.
