Firefox Community Forum

Dear Mozilla Support Community,

This is a rather interesting observation I've recently made, but it appears that with every new software update on my Firefox Developer Edition browser, that I inexplicably (and mysteriously) get signed off/logged off of all my already logged in websites, and while this isn't a major tech issue, per se... It is an annoying one and I would like some clarity on this.

Is there a feature that toggles this on and/or off? Or perhaps, this is a known bug? What is the bottom line on this?

Thank you!

Hey everyone,

I’m running into a frustrating issue with Firefox. Whenever I paste a large amount of text (especially code) in one go, Firefox freezes and becomes unresponsive. This happens frequently in various web apps like ChatGPT and Make.com.

It’s not a one-time thing—it happens consistently when pasting large blocks of text. Has anyone else experienced this? Is this a known issue, or is there a way to fix it? Any tips or workarounds would be greatly appreciated!

Thanks in advance!

Trying out Vertical Tabs, but when doing so an unremovable Flexible Space appears in the Toolbar. You can move it around, but not remove it (image #2 is trying to drag it into the Customise Toolbar icon list). This thing disappears when switching back to Horizontal Tabs.

Any clue why this is happening?

EDIT: I've solved it by installing Kaspersky's extension. I have been troubled by an issue that every time I perform a search on some websites, the page will first freeze for ~10s, during which I can't click on anything on the page. However firefox itself is not totally freezed, like I can switch tabs without any issues, but if I click on the icons of extensions (such as my adblocker) it won't give me any response. After the freeze the page started to load normally. I have tried disabling all extensions, reinstalling firefox, updating to beta, and disabling security.tls.enable_0rtt_data, but none of these works. Other browsers on my device work normally, including Edge and Chrome. Websites that freeze during a search: Google, Bing, Musescore, Duckduckgo Websites that DO NOT freeze during a search: Github, Youtube, Twitter I have encountered this issue both on 117.0.1 and 118.0.

The "font family" property does not change the font of the "option" tag if the font is not installed locally on the computer. I am using Firefox Developer 118 (0b9). Are there any solutions to the problem?

Hello,

I am using Firefox developer edition I noticed it has updated itself to latest version  : 117.0b1(64-bit)

I always have Firefox updates so version before that was the 116.b08

After the update on startup I get the error message attached I close it and then Firefox runs normally but this happens on every time I run Firefox.

Hi, I'm not sure if I just cant find the setting or if this is a feature request. I'm using the Firefox Developer edition, and I during web development I often deal with many query Params in the URL. Is there a way to have a long URL be displayed in multiple lines, or even better, one line per query parameter?

I am developing a website (using AstroJS, but i don't think that's the problem) and since yesterday I am experiencing issues when opening devtools. Once I open devtools the whole FF tab becomes unresponsive, I cannot even refresh the page until they are done loading. I can change devtool tabs from 'inspector' to 'console' to 'network' etc but especially 'network' and 'debug' tabs are blank.

I run a 'performance' capture and got these results. In the test I have only opened the devtools and switched to the inspector tab which is unresponsive. The CPU usage is at around 90% however, I don't really know how to read the finding and understand what the problem is.

So anyone that can help me understand what is going on here?

I am wondering if it is at all possible to adjust the settings when pulling a tab into a new window. For example, if I am running Firefox fullscreen I would like the tab that I pull to be opened in windowed form. I noticed that this is typically the case when using Chromium-based browsers, but noticed that on Firefox it stays in the format as the previous window. (if already windowed the pulled tab will also be windowed) is there a way to ensure that the pulled tab will always be windowed?

When watching youtube or even doing a little task with only one tab the cpu usage from a specific firefox process goes upto 90%. And I have did everything that was given in the following troubleshoot method "https://support.mozilla.org/en-US/kb/firefox-uses-too-much-memory-or-cpu-resources" but still the same result. I tried with troubleshoot mode on with disabling all extensions but the cpu usage was still high. I have also checked with firefox's own task manager tool but there wasn't a single process that was using full cpu. I'll be attaching all screenshots below.

hi!, so i downloaded a couple videos on mozilla, i saw them in my downloads but i didn't open them, now i delete them from mozilla and they were automatically deleted from dowloads and i can't find them in my recycle bin either.Is there a way to get them back?

So I'm running firefox developer edition, and with the same extensions on normal plain firefox, the search results kinda lag behind. If i type fast enough/normal speed, the words underneath the actual typing bar will lag behind. if i type slowly it doesnt do this...

My preferences are set so that "When you open a link, image or media in a new tab, switch to it immediately" is OFF. Therefore most of the time when I Cmd+click on a link, it opens on a new tab that loads in the background. This is what I want.

However, some websites break that behavior. 2 high-profile examples:

• In Google Docs, if a piece of text links to an URL, clicking on the text shows a small window with the URL. Cmd+click on that URL opens it in a new tab, and takes me to that tab.
• In Facebook Messenger, if I Cmd+click on a chat, again the chat opens in a new tab and I'm taken there. Additionally, the original tab activates that chat.

Interestingly, in both these cases, I get the right behavior if I right-click on the URL or in the chat and in the contextual menu choose "Open link in new window/tab/container tab": the new tab stays in the background.

So my question is: does anyone know of a way to always make cmd+click behave just like "Open link in new tab", no matter the website?

I'm on Firefox 115b4 on macOS, but this has been like this for years at least.

Hello, I use both Firefox and Firefox developer edition and in both (different accounts, not synced) in my Firefox I set Persian as an alternative language about a year ago now I can't remove it. The developer edition is just in English but the buttons and some of the text is in Persian (it's the same with Firefox) My laptops default language is English with only Persian keyboard. how can I fix this?

Hi all, I've got a puzzling problem with just one desktop PC on my network, and only in Windows 11 (fully updated) - the same PC when booted into another OS (Ubuntu) works without any issues.

I have a fresh install of the latest Firefox as well as the Developers Edition. MS Edge is also updated to the latest build, yet none of them can load the "accounts.firefox.com" page.

All I get is a completely blank page, save for a blue circle on the top left corner. I've tried all the usual resetting, Troubleshooting Mode... etc, (issue is present in Troubleshooting Mode) and pretty much stumped at this point.

All other websites I've tested with all browsers don't seem to have any issues at all, including the likes of "accounts.microsoft.com" or "accounts.google.com".

Google hasn't turned up with any results matching exactly what I'm seeing with this particular machine/problem... hoping someone can help pointing me in the right direction.

Thanks in advance,

Using latest version of Firefox - 116.0

Unfortunately recently I have been unable to drag files out of the 'Downloads' At the same time, I noticed I can no longer copy images from pages.

I will right click, copy image and it just does not go into my clipboard.

In terms of the Downloads, I'd always download audio or video files and drag them straight into Premiere Pro - I can no longer do this. I cannot drag it outside of Premiere either, so it's not an Adobe bug.

Any help would be greatly appreciated, Thanks
