Firefox Community Forum

I use several browsers and when it comes to functionality I consider FFox to be the best however with 1 major drawback - it's speed / lag issues which is why I stopped using it as my primary browser and only as secondary one

I can have 2 different Chromium based browsers open simultaneously and while this impacts the performance somewhat if I open Firefox and another browser responsiveness grinds to a halt (sometimes even crashes)

Even just starting Firefox by itself takes 5x as long as other browsers

So I'm wondering is Firefox just more resource intensive or is there something wrong with my setup?

The main difference between my Firefox install and my other browsers is the number of Bookmarks (10000s) due to me having it installed for much longer so is it possible for a large number of Bookmarks to slow the browser down even when not open ?

Other possible causes I read elsewhere are 'Cookies and site data' (currently around 50mb)

I clear the 'Temporary cached files' & 'Browsing history' on regular basis so they shouldn't be an issue

The add-ons I have installed are NoScript , Ublock Origin & Firefox Color

In regards to troubleshooting is it possible to install a 2nd install on the same system simultaneously without overwriting the current one ?

Thanks

I have payment methods saved. On payment sites, I click on the CC# input box, and I am given the option to use one of my saved payments. I mouse-over payment choice, and it populates the input boxes with the correct information, however once I actually click the payment method, the payment method and all the input boxes are cleared of all contents. I am therefore forced to enter payment information each and every time I want to use it. The Fill Payment method isn't working.

I have reentered and verified the saved payment method several times.

the tab groups feature doesn't work. WHen i drag one tab onto another, nothing happens, other than the tabs go back and forth. Can't put one tab over another and no group is created.

Hi there.

The original problem is described here: https://support.mozilla.org/en-US/questions/1472503 ( Also the solution I found.)

Jaws and James seem to have left the building.

This problem first occurred with the update from V 135.0.1 to V 136.0 . Currently on V 136.0.4, and every update has exhibited the same behavior.

I have the same issue with two laptops, running Windows 10. Each has been through a few update cycles, and the "Restart to Update" always fails.

So, I close FF, watch for the Resource Monitor to quiet down, and reopen FF.

When I go through this sequence, I notice that the screen will flash once VERY quickly before opening the home page.

FF seems to function normally otherwise.

Thanks for being there,

My monitors are QFD ( 2560 x 1440 ) and I use font scale 125%. With the most recent Firefox these fonts are garbled. They do not display properly. I am using MS Edge for the time being.

I use Gmail, and when I receive a newsletter from the local government, Gmail does not display the images in the newsletter. I've set Gmail to display the images (photographs), so I'm guessing Firefox must have a setting that is blocking the display?

My gyazo extension stopped working .. i can not access my gyazo acc with firefox . i been using gyazo with firefox for years.. I was able to log in using chrome.

Hi,

I am the developer of the Dictionary Anywhere extension which is a Firefox recommended extension. Recently my extension stopped performing up to its expectations due to backend changes in public API that it uses to find meaning of the words.

However, I am unable to modify the code of extension to fix the issue as I am not able to login to my account due to it being behind MFA, and I have lost access to the phone which contains those MFA codes.

Can something be done here, to allow me to update the extension to rectify the issue that 50k users who use this extension regularly are facing? For example, can the extension be transferred to another account through which it can be updated, lots of users are suffering as the extension is not working. I have access to the source code of the extension .

Thanks and Regards

Since April 5th I have lost spell check in the message pane of the emails I type on outlook.live.com It still works in the subject line, but not the message area.

Windows 10 pro 22H2 updated to end of March, when spell check was still working well. Firefox 137.1 English Canada Language selected (has worked well for years)

I go to outlook.live.com to read and answer my @hotmail.com emails.

When right clicking on a misspelled word in the message area I get only these options, Firefox does not give me the usual options.

I am currently having other problems on that site, clearing outlook.live.com cookies does not clear the problems.

I have Dark Reader installed and it works perfectly almost anywhere, but ironically, Firefox' support forum itself comes out all white regardless if it's on or off?

I'm on OpenSuse Leap 15.6 with KDE Plasma 5.27.11.

I have a question about using Firefox PDF Editor. I copied some text from a PDF document that is on my computer, by highlighting the text and then hitting Ctrl+C. The text copied onto my clipboard OK. Then I opened a blank PDF document in the Firefox PDF Editor and tried to paste that text into the blank document, but I wasn't able to do so because when I right-clicked on the blank document and then clicked on "paste", nothing happened. This apparently is because the word "paste" is faded-out in the drop-down menu (i.e., it does not appear in prominent bold print). Google's Artificial Intelligence seems to indicate that the technique I used would work (see screenshot which I've uploaded). But it didn't work, so can anyone please tell me how can I paste text into that blank document?

All,

Noticed a major problem in Fire Fox, that must be corrected! I usually have 2-20 FF sessions open and 5-20 tabs also open in each FF session. FF used to let you see up to about 15 tabs, displaying them and responsively compressing the width of the tabs,to let you see what is open, but now it only displays 3 tabs, requiring you to actually scroll right or left to find the tabs open.

Totally unacceptable! This maybe OK for NEWBIES, but we pros and Developers need to see everything without scrolling to find it.

Otherwise I totally need a different Browser!

While using Outlook.com email in my Firefox browser, I attach a zip file to send to someone.

They reported that the zip file is empty. This happened two more times.

I confirmed that the zip file that I was uploading from my hard drive did indeed have files included.

I then downloaded the attached zip file from the email in my "Sent" folder. It was empty.

When I tried using "Outlook.com" in the Chrome browser, I did not have the same problem.

I'm using Firefox ESR version 128.9.0, on Windows 10.

(The downloaded empty zip file also had "utf-8" added to the file name - that problem is addressed in other tickets and is being worked on. I am not asking about that.)

Last week, all 11 of my Firefox extensions, which I've been using for years, were suddenly disabled. For each I got the same message: "[Extension name] could not be verified for use in Firefox and has been disabled." Following Firefox's instructions, in about:config I switched "extensions.langpacks.signatures.required" to FALSE, restarted my computer, but nothing changed. I tried reinstalling the extension Adblock Plus from Firefox's own list of add-ons, got the message "Installation aborted because the add-on appears to be corrupt." Any idea what's going on and what I can do?? Thank you.

iMac OS 10.11.6 El Capitan; Firefox version 78.15.0esr (64-bit)

On my Macbook Pro — OS 12.7.6 Monterey, Firefox version 136.0.2 (64-bit) — the same extensions work just fine.

I use Primary Passwords on important sites. Since v136 installed this morning, no matter what site I OPEN Firefox to, even search sites, the Primary Password is requested. If Firefox is already opened, if I open the "unimportant" site, no password is requested.

Having issues with my Bluetooth AirPods and sound in Firefox. The problem being there is no sound when the device is connected and watching a YouTube video for instance. Things went wonky after the recent update to 133.0.3. At first there was no sound period. Then somehow, not even sure how, I saw that Firefox was muted in Windows (11 Pro) settings. That's a mystery unto itself since I'd never previously gone to that area. Now that I have volume through external speakers working, audio through AirPods doesn't. Everything works fine using Edge and audio from music. I know the device is connected and when that is, it's the default for where sound comes from. Used the test thing and yup there is audio. Is there something I'm missing? There must be but I can't figure out what it is. Hopefully someone reading this can point me in the right direction of resolving this issue. Thank you in advance.

Chrome seamlessly harmonizes with the PowerToys FancyZones feature in Windows 11. In Chrome, I can drag a tab out of a browser window, and instantly snap it into a FancyZone. I can also quickly arrange multiple separate Chrome windows into FancyZones without issue.

Firefox's interaction with FancyZones is not good. When I drag a tab out of a window, it doesn't allow me to snap it into a FancyZone. I first need to release left click, allowing the tab's new window to appear, then I can snap that window into a FancyZone.

The biggest occurs when I have multiple Firefox windows open and snap one of them into a FancyZone. Often, one of the open Firefox windows will spontaneously shrink itself in size. When I try to manually resize the window back to normal, it shrinks further and further, until it is an invisible sliver. The only solution when this occurs is to fully restart Firefox.

It seems strange that Firefox has such poor compatibility with FancyZones, which is growing in popularity along with other productivity tools in PowerToys. Wondering if anyone else has experienced these issues, if there is any workaround, or if there is a fix being worked on.

When using Google Meet in Firefox browser, I am only able to share my window, not my screen. When I choose "share screen", it says I must change my permissions - but my permissions settings have not changed and this is a problem I have started having only in the last few days.

I do not know where I am supposed to change these permissions settings.

I have checked my permissions in settings > privacy & security > permissions - there is nothing there about screen sharing.

I have checked my permissions in padlock > connection > more information > permissions and the only options I have for screen sharing are "always ask" (default), which is set. The only other option I have is "block" which is not set.

My Firefox browser is up-to-date.

Can anyone help? Thanks!
