Firefox Support Forum

Hello,

I've just downloaded firefox, making the switch from chrome. Doing so I've migrated a couple of tabs and extensions I had. Totally it was 50 tabs, with 6 extensions, I've downgraded now with the switch and it's only 37 tabs and 2 extensions, even so firefox is using more ram than google by a large amount. With 50 tabs open, chrome was using 1.5gigabytes of memory. With the same 37 tabs and extensions, firefox is currently using 6 gigabytes of memory.

The tabs used are from reputable sources, so firefox shouldn't be breaking on these websites. The extensions I am using at the moment on firefox is, Ublock origin, Dark Reader.

As far as reputation goes, firefox should be using less Ram than chrome. Is there a setting I should know about to lower such performance issues? Firefox acceleration is ON.

Thank you for any answers.

The main youtube page loads and displays ok. As soon as a video is played (even in preview), firefox crashes. I'm on Linux Manjaro. other websites with video work fine (for ex Vimeo) I tried disabling all my addons and plugins in the normal mode (not troubleshoot mode) and it still crashes. However, the troubleshoot mode works fine ! Refreshing firefox didn't fix the issue. I have another computer with Linux manjaro and firefox works just fine. I spent a lot of time trying to understand what's wrong but I really don't see why.

Thanks in advance for your help.

I am unable to sign into Microsoft 365 services in Firefox. When I try to sign in on the Microsoft 365 Website, it doesn't sign in, it simply redirects me back to the website. When I try to sign in from the Outlook login page, I get an error page saying "500 Something went wrong. Repeating redirects detected." Screenshot attached.

1. I was able to sign in with another browser. 2. I was able to sign in on a device running Windows 10. 3. I have cleared the entire cache and history on the Firefox browser - it didn't work. 4. I tried logging in with Firefox in Troubleshooting Mode - it didn't work.

I saw an archived thread from 10/28/2021 where @OthelloBloke had the same issue ("Microsoft 365 Signin on Office.com Doesn't Work After Windows 11 Update"). It didn't seem to have been resolved. It has been a while since Windows 11 came out. Has there been any resolution to this issue? Please help me fix it. Most of my activities are on Microsoft 365, and I prefer to use Firefox as my browser. But if this is ongoing I will need to abandon this browser in order to access my work.

i somehow can't find the 'mozilla' folder in 'appdata/roaming'. i was trying to open my profile folder but it displays the message saying that it's 'unavailable'. i digged in further into the problem and found out that i had no such mozilla folder in appdata. is there any way to fix this problem? or am i just missing something?

Dear Firefox Team, good morning.

I hope you are doing well and that you are all healthy.

Guys... while looking for a way to measure the performance of our site, we came across the Core Web Vitals (CWV) some time ago. These are Google KPIs for measuring the user experience on a page (https://web.dev/vitals/#core-web-vitals). Unfortunately, some of the KPIs (like the Largest Contentful Paint or Cumulative Layout Shift) are currently only accessible using Chrome and it's preformance API. That's a pity, because there are also many people using Firefox who visit our site... and it would be interesting to have such KPIs as well.

In an article by Cloudflare (https://developers.cloudflare.com/analytics/web-analytics/understanding-web-analytics/core-web-vitals/) we recently learned that Firefox is also planning to expose the metrics used in the CWV... only the "coming soon" from the article is a bit vague. That's why I'm contacting you to get some more information on that topic. Do you perhaps know whether the topic is planned and will be tackled this year?

Thank you for your attention. Best regards, Carlos

Hi. After recent update I started to see issue where blue/white border is present when clicking web site elements. Ususally this kind of border is present if you select elements via keybaord but in this case it's present when clicking elements with mouse. It usually stop doing this if I close and reopen FF but not for long. Example is in posted screenshot. I have not altered my settings in any way.

I've been professional web developer for almost 15 years. I've wanted to try to step away from Chrome, but I'm having a hard time navigating through basic functionality with Firefox's developer tools. One of those was a simple "Control + F" find feature. Am I missing something?

Specifically, lets say I want to search for a specific class within a style sheet. In Chrome I can bring up the dev tools, select the style sheet, Control + F, and it will give me a toolbar with options to step through each instance of the class. It gives me total count and I can hit the up or down arrow to cycle through each instance of that class (insert any selector here). I can also Replace an instance or all instances.

When I try this in Firefox's dev tools, I get the first instance but see no way to do anything else. If I hit enter it doesn't cycle through to the next instance but creates a line break in my style sheet.

I've researched with no success. I know there is the filter option but that isn't what I'm looking for in this case. Any help would be greatly appreciated.

Since the OS upgrade, any portal that I open (especially the ones that I have my user id and password saved) crashes. One crash report can be found at https://crash-stats.mozilla.org/report/index/7d671357-2d98-4bbc-b177-4029e0221221

I have tried disabling add-ons/ exensions, disabling auto-fill, downgrading security, reinstalling (even the ESR edition), deleting Firefox files from the library/application_support - but it doesn't simply work. Not sure if this is an OS issue.

Any ideas would really help. Getting the below info on the about:crashes each time:

Crash Reason EXC_BAD_ACCESS / KERN_INVALID_ADDRESS Crash Address 0x0000000000000018

I can connect bluetooth devices to my SurfaceGo and successfully direct audio output to them using Chrome, Edge, or internal sound files. But in Firefox the audio only goes thru the internal speaker no matter which audio output device I select. Is there some setting I need to fix so that Firefox will speak to bluetooth devices?

Getting unreadable text when website is using a font that isn't installed (see attached screenshot). When I view the source in developer tools it uses Roboto (which I haven't installed).

On my Mac, I have tried other browsers (Chrome and Safari) and they work fine. I have also tried this website with Firefox on Windows and it also works fine.

I have had 2 sites produce this error box in place of the target Web Site (See Picture). I have read previous topics about this and have followed the instructions with no positive results. FYI, clearing the web site's cookies, clearing Cache and disabling Hardware acceleration.

The first was https://www.walmart.com. After leaving a "Feedback" 2 weeks ago it appears as if they were able to fix the problem. However, the site is not as important as my Medicare PPO provider. I tried loading previous versions of Firefox, but that did not help.

In both instances the LOL "support" people's response was to try a different Browser. So, I reluctantly loaded Google Chrome and it worked perfectly. From my perspective, this eliminates everything to do with my machine setup.

Below is the sign-on URL (not unique to me). Please note that this 668 character URL has not changed for over a year. It is just Aetna's adoption of the Imperva Security Firewall. Both my Winders 8.1 and Winders 10 machines produce the identical results.

I am prevented from downloading an important document because the site says that I need to disable an ad blocker. I am not aware of having an ad blocker and nothing shows up in add ons and extensions. How do I find and disable an ad blocker that I cannot find?

Hello all,

I'm running Version 108.0.1 on a mid 2015 Macbook Pro MacOS 12.6.2 Today I went to do a translation using the "to google translate" add-on and noticed it was missing from its place in the context menu. I go to "get more add-ons and re-installed it.

So why was it uninstalled without my consent? What can I do to stop this happening again?

TIA, Gene

Any Safe ...As.. in my Firefox isn't working. Nor from right mouse click, nor from menu-file. Currently I'm with 108 under XFCE(Ubuntu). But the troubles was may be after 98. I've disabled all extensions - persist. I tried also Troubleshooting mode - still persist. I've tried reinstalling - persist. Where have to look? With Chromium I do not have such troubles. Thank you!

I am making a web page (in Dreamweaver) for a meeting and I have certain things in bold. In Firefox, the bold (<b></b>) does not show. Bold shows up on my pages on Chrome and on Microsoft edge. I've also tried the <strong> tag, but that doesn't work either. The font family for the pages is sans-serf. I really need this to show on most browsers.

I have renewed my driver's license online and am ready to print the temporary version; however, when I click Print, I am told that I need to allow popups. I have no idea how to do this. I need help ASAP!

after the last update, the keyboard shortcut shift+esc opens the processes menu. i would like to disable it - this is the same shortcut that i frequently need to use on a specific website, and needing to close the processes menu every time is deeply annoying

For some reason, with no prompting I'm aware of, the click and drag scrolling feature of the middle mouse button has stopped working, solely in Firefox. It works fine in other programs, such as Steam or Edge. The error persists across multiple mice, and while in troubleshoot mode. Middle click by itself does work, opening and closing tabs with no issues. I'm fully updated, both Windows and Firefox. I haven't tried reinstalling yet, but I wanted to ask if there was any other known fix I didn't manage to find.
