Firefox Community Forum

I've tried to search and found some other posts about this, but not a ton... leading me to believe there is something wrong.

Issue: Fonts on some sites are too heavy/bold (vs appearing correctly on Chrome/Chromium browsers) Environment: Windows 10 or 11, Firefox stable (currently 105.0.1) Example site: https://www.subaruoutback.org (this is not the only one, just an example) Workaround(s): I can do one of two things... I can either enforce browser fonts globally, which fixes the issue but then also break some sites in other ways or I can use an add-on to let me selectively enforce browser fonts as needed (which is what I am doing).

Screenshots attached, this is my experience on multiple PCs (Windows 10 and 11). One image is from Firefox, one is from Chrome.

On some sites, it isn't a huge deal... maybe just looks bad but is functionally fine. On some sites the issue is more impactful and actually creates readability issues.

Of course I can continue to work around the issue, but ideally I would like to fix it.

I did read that there are some changes site owners can make for font handling, but obviously requesting that sort of thing isn't realistic in a general sense.

Thank you!

Moving from Windows to Linux and in the process moving from Chrome to Firefox. In Linux, there seems to be an issue where Firefox isn't recognizing that I have installed Chrome. No problem, I went into Windows to do the move instead. But since the data isn't saved and you have to have an instance of Firefox running (?) to actually sync, I decided to download Firefox on my iPhone, get my passwords from Chrome, then sync to my iPhone, boot back to Linux, then sync on Linux with the data on my iPhone, and somehow in the process locked myself out of logging into Firefox on my iPhone due to how many times I've had to log in to Firefox to figure out this convoluted and broken process. People are wanting to switch to Firefox due to ad blocking support, and this is a massive barrier to entry. Can we just fix importing from a csv file?

I got a new computer so I created an acct and set all my open tabs and history to sync. It wasn't intuitive to my not techie brain, but found out how to open all the tabs on the new computer. However, they don't open in the same order (makes it almost useless when you have a lot of tabs), and the tabs don't have their associated history.

Is there some way to have Firefox open tabs and history in the same state on the new device?

I am honestly in chock with Firefox's terrible decision of not providing any option for the user to delete downloaded files.

It is honestly amazing that they came up with such a terrible decision. My downloads folder is a complete mess now and there seems to be no way to fix this.

I don't understand why not just provide an option for the user to only open files. People should be able to choose their settings.

I refereed to this previous post and the solution there didn't work: https://support.mozilla.org/en-US/questions/1370409. By setting browser.download.improvements_to_download_panel to false.

Is there actually no way to only open files now?

Hey!

Thank for being here I hope you can help me because firefox was always my favorite browser One of my favorite sites is soundcloud.com Recently, when i try to go there i get after a minute try to content a massage from the site, with their logo and everything- "oh no!

I hope you can help me Thank you!!

While exploring about pages in Firefox, I came across about:profiling. I'm not sure what exactly it does, but since I've been to it, a profiler icon has been added to the toolbar and I can't find any way to get rid of it completely (only ways are to hide it). If it could be added, there must also be a way to remove it? How can I close it?

If i move the directory to anywhere else it launches In the default location it wont launch - No errors - cannot launch in profile manager mode - cannot launch via cmd - cannot by going to C:\Program Files\Mozilla Firefox\ and launching firefox.exe literally nothing happens

As far as I can tell, this has something to do with Firefox aggressively offloading stuff from memory to storage. When I alt-tab at times, Firefox completely freezes. Every Firefox window hangs on a single image and I am unable to interact with anything for a few seconds. During these seconds, I can see the memory % in the Windows Task Manager slowly climbing until Firefox unfreezes itself, so it seems to be loading stuff back into memory. For example, it'll climb from 55% to 70%, taking its sweet sweet time. I also see some disk usage with 'System' during this time.

This behavior occurs even when I'm active on the browser and at 50% memory. It seems to occur more often once I hit the 60% memory mark.

I'm almost certain that this is a Firefox-specific issue, because I can interact with any other program during this period. It is only Firefox that stops dead in its track.

Is there a way to make this behavior less aggressive? I'd rather not have my alt-tabs freeze every few minutes.

On many websites Firefox does not display checkmarks in boxes, won't show color options when ordering items that have different available colors, just shows white, also for cars when looking at options won't display the color options just the boxes (or circles) to check. Other issues also on many sites does not always work have to switch to Safari. I have a Mac mini Big Sur 11.6.6. As a matter of fact just below on this very page trying to check box that says e-mail me when somewone responds and nothing shows when I click on it.

Firefox stopped working today. Every time I launch it, it responds with: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window."

I launched Task Manager and killed the active processes, relaunched ff - did not resolve the issue.

I have uninstalled and reinstalled ff multiple times - did not resolve the issue.

I have removed the lock as per here: https://support.mozilla.org/en-US/kb/firefox-already-running-not-responding#:~:text=Right%2Dclick%20on%20an%20empty,it)%20and%20click%20End%20Process.

I have verified the access rights as per here: https://www.minitool.com/news/fix-firefox-is-already-running-but-is-not-responding.html

I have completely removed all the mozilla entries from both Program Files AND in the registry, then reinstalled. did not resolve the issue. registry instructions from here: https://www.reddit.com/r/firefox/comments/s9lguc/how_to_completely_uninstall_firefox/

I have tried to delete existing profiles AND create a new profile but I always get an error: "An unexpected error has prevented your changes from being saved." https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles#w_start-the-profile-manager-when-firefox-is-closed

I'm out of things to try. Hate to abandon Firefox but I'm at the end of my capabilities.

checking box within a Tab on yahoo mail will immediately open that entry and then freeze further operation until the screen is shut down. This happens on my wife's HP lap top i5 Pavilion 4.00 ram. ie: inbox tab will show a number of email - a dozen or so - followed by grey empty areas. The tab indicates 100+ total in inbox. Selecting one box opens the email but locks up any activity on that email & must be shut down to exit. The identical situation happens when I access my email on her machine. She is using Firefox 105.0.1 HOWEVER, on my machine, HP desktop AMD A8 8.00 Ram, both email addresses do not lock up, multiple boxes can be checked and work as expected. My desk top uses Firefox 104.4 This began happening within the past couple of weeks and I can not debug the situation. Any pointers ??

I installed mozilla today and I looked in to my settings and found this message "Your browser is being managed by your organization."

I am not part of any organization since this is my home pc.

I checked the forums but i couldn't solve this.

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox and HKEY_CURRENT_USER\SOFTWARE\Policies\Mozilla\Firefox doesn't exist for me and i don't use avast.

On about:policies it shows "Certificates-ImportEnterpriseRoots-true"

What is this ImportEnterpriseRoots thing?

I'm using a laptop with windows 11.

Can anyone help?

I just made the switch from Chrome to Firefox, and I'm still trying to understand the small differences that exist between the 2 browsers.

While on Twitter, what I usually do is middle-click with my mouse on a Tweet to a new tab that I want to look into later, then continue scrolling down my timeline, then check out the Tweets I opened in the new tab(s). However, when I try to do the same thing on Firefox, it automatically opens the new tab. Because of how Twitter works, this also reloads the Home page when I opened it up, so I just lose anything I was just looking at when I opened the Tweet in a new tab.

What can I do differently here?

Hello,

i have a problem with Rightmove.co.uk webpages. On the webpage where you can see house plans, I zoom into the plan, and the plan just cannot be moved anymore and zoomed as well. I entered Firefox in troubleshooting mode without any extensions enabled and the same issue happened still. I tested the Brave and Chrome, no problems there. I tested Firefox latest version and also the ESR version, both had the same issue. One of the webpage links is below that just freezes, but the same issue happens with all sites when you want to see house plans. https://www.rightmove.co.uk/properties/125021075#/floorplan?activePlan=1&channel=RES_BUY Please help me.

Thank you. itaavo

I'm trying to watch videos in Firefox. Youtube works but Xvideos does not. Firefox pops up a window asking me:

>> "Opening xvideos"."com ###.mp4". >> which is: MP4 Video (16.4MB) >> from https://cdn77-vid.xvideos-cdn"."com >> >> What should Firefox do with this file?

My only choice is: Open with Windows Media Player x86 (default)

suggestions?

I'm running Windows 7 Firefox 76.0.1

Thanks!!!!

Can't connect with the just downloaded version 66.0.4 to virtually any site - not to Google, not to NYT, not even to Mozilla - Firefox won't accept ANY certificate! Following errors appear (examples): "Did Not Connect: Potential Security Issue Firefox detected a potential security threat and did not continue to addons.cdn.mozilla.net because this web site requires a secure connection. What can you do about it? addons.cdn.mozilla.net has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site. The issue is most likely with the web site, and there is nothing you can do to resolve it. If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the web site’s administrator about the problem.

Or: Warning: Potential Security Risk Ahead Firefox detected a potential security threat and did not continue to www.nytimes.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details. What can you do about it?

If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the web site’s administrator about the problem.

The explanation is as follows: Someone could be trying to impersonate the site and you should not continue. Web sites prove their identity via certificates. Firefox does not trust www.nytimes.com because its certificate issuer is unknown, the certificate is self-signed, or the server is not sending the correct intermediate certificates.

No problems whatever with other browsers. I'm sending this with Safari.

I used this tablet for many years and got lots of bookmarks on my browser, but recently its antenna stopped working. I did some research and found out you can export the bookmarks from firefox even if you cant connect to the internet to use the sync functionality. I rooted the phone, copied the browser.db file from firefox and exported the bookmarks table with SQLite Browser. I read on some verry old (6-8 Years ago) threads on this forum that they imported the bookmarks.csv they got from the db in excel, then modified it in some sense and then exported it to a html file to import that in firefox. I did everything to where i have the whole table in excel, only need to know what i need to modify in it.

Hello, I use Firefox 105 on my PC. I have embedded various YouTube videos on my website. I've had the following problem for a few days: I can see my videos on both my smartphone and tablet without going to YouTube. On my PC (Win 10 Pro Vers. 21H2) the display wheel "rolls" without opening the video (... "an error has occurred, try again later"). But if I click on: "Watch on YouTube" plays the video via YouTube correctly. Does anyone have any idea what might be causing this? Is there a wrong setting in the Firefox browser? Many thanks and best regards Helmut
