Firefox Support Forum

When i go to open a PDF file with Firefox, the text renders incorrectly (see image) for most PDF files, but not all (i'm not sure why. And this only happens with the Flatpak version of Firefox [1]. It doesn't happen with Firefox ESR (DEB version from my distribution) [2] and it doesn't happen if i view the same PDF file with pdf.js in a non-Firefox Flatpak app (GNOME Web) [3].

I've tried reinstalling and tried starting in troubleshoot mode, but neither seemed to fix the issue.

[1]:

• Name: Firefox
• Version: 117.0
• Distribution ID: mozilla-flatpak

[2]:

• Name: Firefox
• Version: 102.15.0esr
• Distribution ID: BLANK (preinstalled with Debian Linux 12)

[3]:

• Name: GNOME Web (Flatpak)
• Version: 44.6

I don't know why, but since today firefox keeps reloading all my tabs I have open every couple of minutes. It happens on both my desktop and laptop and its getting annoying. I also disabled the auto refresh in config, along with clearing the cache. I uninstall the plugins that I installed last week, and still happens.

Hiya. I usually have a fairly large number of tabs open on the browser. I use the Panorama View add-on for tab management. Usually this means that on any given container I have about 10-20 tabs open for a total of some 300 odd tabs. The nice thing is that Firefox doesn't usually load all my tabs so this works out for me. Recently however something weird's been going on and Firefox just refreshed ALL my tabs across all the containers. This kills my performance completely, especially given a fair number of tabs are just random youtube links. When all my tabs are open Firefox eats up like 25 GB of RAM, which is understandably not great.

I tried refreshing Firefox to no avail. Is there any way to stop this constant loading of all tabs?

I use Firefox on two computers, synced. Both computers are experiencing this issue. My browser will, at seemingly random intervals, refresh all tabs, which causes me often to lose my work on whatever I was doing. I have gone to about:config and turned off the auto-refresh preference, but the problem still persists. Please help, I don't want to switch to another browser but I will if this problem persists as it is QUITE frustrating.

Hi, I'm having this issue with Firefox where it will try to reload/load all my tabs and my system CPU usage will jump to 100% in the about:performance page it will show Firefox at 140% CPU usage. I've tried to reinstall, Firefox. I've also tried removing extensions, as that's where I think the problem might be coming from. But it didn't seem to solve anything. I've also gone into about:config and set blockautorefresh to true, but this didn't help either. I went into about:performance and extracted one of the profile performances for the Firefox system. Furthermore, I am not knowledgeable about Firefox and/or web development and the services to understand and isolate the problem causing this issue. I'm running on macOS, and I've only recently switched to Firefox, as I used to run Arc as my primary browser. Has anyone had any similar issues with this and are there any fixes that might work to prevent this from happening? It severely impacts my work as I'm not able to use Firefox until I restart it, and that would be happening every 10–15 minutes.

Hi

Property listings from the site www.realestate.com.au seem to have an issue loading the map in the latest update.

I usually do my searches with the below filters but am getting the attached error. https://www.realestate.com.au/buy/property-house-with-3-bedrooms-between-500000-1200000/map-1?numParkingSpaces=2&misc=ex-under-contract&boundingBox=-27.383978390981,152.91747024644357,-27.471055349397094,153.13719680894357&source=refinement&sourcePage=map&sourceElement=location-tile-search

Individual property pages are also showing that the map could not be loaded: eg. https://www.realestate.com.au/property-apartment-wa-scarborough-142778884

I'm running version 117. I've tried clearing cache/cookies already. Issue is also happening on my macbook running the same version. Other browsers are displaying the maps as intended.

Thanks!

Hi,

I've noticed since the latest update, when click on a link or search for something, there is a delay.

Is there anything I can do but it doesn't happen to all sites but annoying.

This doesn't happen with Chrome.

After updating firefox to 112 it now starts with ugly white ui dummy before actually loading proper UI. Screenshot attached. It was not happening on firefox 111.0.1. It happens every time I launch firefox 112. Of course nothing in changelog is said about changing performance or UI so I have no idea what is causing this.

hello! i've been having an issue with mozilla where webp images are not loading at all. this is especially prevalent on youtube, where thumbnails simply do not load, as well as on tumblr, where if an image or gif is a webp file, it will refuse to load. both are attached in the image below to see the difference between firefox and chrome, as the images load fine on chrome. as well as that, discord, when opened with browser instead of the app, does not load profile pictures, server icons, or custom emojis. google hadn't helped me at all, and i don't know what to do at this point. i don't want to go back to using chrome.

in the attached image, the top images show a set of shark sculptures. the first does not load on mozilla, and looking at the image file, it is a webp. the second image is revealed to be a jpg, which mozilla treats normally. in the second set of images, there's a quick look at a random youtuber's page, the top being mozilla and the bottom being chrome, and you can see the mozilla thumbnails do not load.

thank you for reading! i'm very confused and am unsure what to do. any help is appreciated!

Not sure when it started but nearly every attempt to play Youtube videos results in the video freezing after about 1/2 second while audio continues, then the video jumps forward randomly before freezing again. Have reloaded, restarted, cleared history, cookies, etc, and nothing helps. Mean time Chrome plays the videos flawlessly. This is a recent problem with FF and needs fixing badly as it will just not go away.

My Firefox keep "freezing" when I press enter in Google Search. Firefox doesn't freeze since I can still scroll up and down, and I can still access my other tabs. I tried the other solutions suggest on reddit or firefox fourms, but nothing works.

I reinstalled, reset the profiles, deleted all extensions and nothing works.

I am using Firefox Nightly 119.0a1 (2023-09-04) on macOS 12.6.8 on an Intel 15' MBP.

When clicking on a link from an external app (eg. WhatsApp, Teams, etc.) with Firefox not running in the background, Firefox will open up but will not open the link. I have to go back to the app and click the link again for it to work.

This has been an issue for me for a while now and it only happens with Firefox as other browsers will work as expected.

Every now and then every tab on firefox would just refresh at once. I would be watching a youtube video or just browsing the web when everything just freezes and then refreshes and I would see the loading icon on every tab.

Hello, I've been trying to use my Firefox browser for the past week and nothing I do seems to work. Whenever I click the icon on my Windows desktop, it sends me the following Mozilla Crash Report:

We're Sorry

Firefox had a problem and crashed. We'll try to restore your tabs and windows when it restarts.

To help us diagnose and fix the problem, you can send us a crash report.

I've restarted my computer and tried to change multiple settings, but the same pop up message keeps appearing. I've checked the box that sends the crash to Mozilla and clicked the button that says Restart Firefox, but still nothing. There's also a "Detail" button that provides a bunch of information that I'm not sure how to interpret haha but I can try to copy that if you think it would be helpful.

I would appreciate any help. I'm looking to get a new computer (not sure if that is part of the issue), but I'm really hoping to be able to save the bookmarks I had.

Thank you.

Intermittently (maybe 1/20 times?), when I try to do a Google search from the URL bar I'll get a tab that doesn't load for about 30 seconds. If I search for the exact same thing in another tab it will load instantly, and if I select the url and press enter it will also load instantly. I am seeing this issue both when entering a search and when selecting text and clicking "Search Google for X".

I found a recommendation on a similar issue to set security.tls.enable_0rtt_data = false in about:config but I have seen no change with that setting.

Firefox 117.0 Windows 10

When using Google search the screen locks and the cpu goes high. After approx 45 seconds the results are displayed. This does not happen using DuckDuckGo as the search engine. Google search is fine in Pale Moon and Edge. I have attached screen prints of the Firefox screen (the connection circle is constantly rotating during the 45 seconds) and a screen shot of Task Manager. This has only started happening since updating to 117 yesterday.

Thank you

I'm having an issue with a particular text field. When entering any text into said text field, my CPU will shoot to 100% usage on some cores, hang for a bit and then print the text after a few seconds. I have an Intel 13900k @ 5.5ghz.

I can't provide a link to the text box as it's a WordPress CMS on my local machine. This issue does not present itself on the competitor browser.

A few troubleshooting steps I've taken:

• Re-install Firefox
• New profile
• Disable all extensions
• PC safemode + Firefox safe mode
• Tested dev/nightly/stable (I'm using BETA daily)
• Disabled accel

Hopefully I'm able to have an expert look at my profiler to help determine what the issue is. I'm not knowledgeable in this area unfortunately. https://share.firefox.dev/3s60ISV

Thank you.

Hello, Since i updated to firefox 117 im having this isue.

I have an HTML in a local ngix server, that pulls camera feed from 2 diferent ZoneMinder servers. Super simple HTML that works OK in ver 116 (i also downgraded to test)

I couldnt find a value in about:config that re enables this.

It seems firefox is not displaying images that are located in a diferent IP Address than the main html. It displays the images correctly if the html is in the same server than the camera feed, but since i have 2 diferent image sources, i cant make it work that way.

Firefox Nightly is not displaying the images also.

any ideas? something to try?

Thanks in advance, Nicolas

Every time I restart Firefox, places.sqlite which is currently 105MBs changes to only 5MBs and a new file named places.sqlite.corrupt appears. If I open Firefox, all my history is gone. If I rename the .corrupt file to places.sqlite my history comes back. I want to know why it gets corrupted? It happens when Firefox closes and it doesn't matter if there's a power cut, closing with X , or Exit, Firefox restarts and I have to rename the places.sqlite.corrupt file again. This has been happening for almost two years now. My computer stays on 24/7 and I may restart it once every 2-3 months, but sometimes you have to restart it many times a day because of issues and it's a pain in the behind to rename the places.sqlite.corrupt every single time. Any ideas?! Could an add-on be affecting it? I don't have a lot of them. Just basic AdBlocks.

Thank you.

I am running Firefox (Flatpak) on Debian 12 and I use a Nelko thermal label printer. I had installed nelko-printer-driver previously and had no issues printing on Firefox but, due to an issue with Debian, I had to reinstall Debian 12. Now, when I try to print a document then Firefox immediately crashes. I have tried:

• Uninstalling the Flatpak and deleting app data
• Help > More Troubleshooting... > Clear Saved Print Settings
• about:config > Reset modified printer settings
• Uninstalled/reinstalled nelko-printer-driver
• Restarted
