I run the latest version of Firefox.

Lately it refuses to open on first attempt - be it from a start menu link or double-clicking the shortcut on my desktop or trying to open a html file directly.

It's annoying and i'd like to fix it.

I've done all the usual stuff like clearing the cache.

During normal use, my Firefox looks... normal. See first attached image. But when I start typing in the address bar, everything but the address bar disappears. See second attached image. Is this behavior intentional? If so, which version introduced this behavior? And how do I disable it?

I have Firefox installed on multiple devices and most/all of them don't keep sessions or browsing history

I noticed that these files are updated while browser is open and get deleted once browser is closed:

• sessionstore-backups/recovery.baklz4
• sessionstore-backups/recovery.jsonlz4

No other files are related to sessions

I have "Open previous windows and tabs" checked

Installations:

• Windows 10
• Debian 12
• Debian 13 (Firefox 148.0 Snap)

On Firefox for Android, this issue doesn't happen, I can even see the whole browsing history including history lost on PC installations

The bookmarks sidebar disappearing is creating inconvenience and I´m always having to use CNTL-B to recover it, even after I have selected View/Sidebar/Bookmarks which has a tick. Each time I change sites it deletes the tick.

I checked the about:config toobars and I cannot find it, or am I in the wrong place ?

Hi team,

I am a researcher and trying to collect data from crash-stats.mozilla.org for my research. However, I got 403 Forbidden for several days. Can you help me to resolve this? Thank you in advance.

Hello! Several days ago I had to make a new Win10 computer account and being that when my FireFox reinstalled all my settings from my FireFox Account after signing in I noticed the small search bar at the top where you could use a different search engine was missing. I have been racking my brain to figure how to get it back. Could someone be so kind as to let me know how do I get the small search bar back at the top. Thank you.

Respectfully, Don

Prior to the 6/16/25 release, hitting the back button on the three button control on a page with no previous pages would open the home page without closing the current tab. After the update, it closes the tab before opening the home page. This was useful for quickly opening multiple tabs, as well as preventing accidentaly closing a tab. Please revert this change, or make it a setting.

This topic appears to show up a few times, but none of the solutions work for me (e.g. they were using A/V or "it just worked"). The error I get is also different.

This a pretty fresh install (migrating from Chrome so I'm currently re-logging into all my sites to ensure I can access everything I need.. and going through MFA hell heheheheh).

Everything is mostly fine, except for Synchrony Bank.

I go to login at https://auth.synchronybank.com/account/login, enter _any_ username or password (doesn't matter if I enter the right details or the wrong ones), and as soon as I click "sign in" I get an error page

Looking in developer console, the error reason given is NS_ERROR_NET_INTERRUPT while trying to POST to auth.synchronybank.com. Every so often I get PR_IO_TIMEOUT_ERROR but over 90% of the time it's NET_INTERRUPT.

This occurs also in private browsing and also in safe mode. I even created a new profile and tested it from there; same issue.

I've tried lots of things related to this (e.g. setting network.http.http3.enable to false), added the domain to the advanced tracking exception list, and I'm running out of ideas.

I can see traffic flowing to akamai but (it being https) I can't see what's inside the traffic. Could akamai be objecting to something in the content?

FWIW, I can login with Chrome on the same machine.

I am starting to use the new utility which allows me to group tabs. But I would like to see only the name of the group and not the whole list. How can I collapse the list of tabs which belong to a group leaving only the group name shown. Then with a click I should be able to see the corresponding list of tabs if I need it. Saving and closing a group is not a solution, as the group disappears from the Sidebar. Thank you for your help. Best regards Ray Ballisti [edited] @bluewin.ch Switzerland

Is it possible to view the contents of two tabs simultaneously? I have been in many situations where it would be very helpful to view two different web pages side-by-side to more easily make comparisons. Opening a new window and viewing them side-by-side is similar but being able to pick two tabs to view in one browser would be a lot faster and easier to control.

This happened too much, like 6 times when using firefox in this month. I dont want to shut the program because I got unsaved notes in it. I was listening to music and it just began to play it non stop. and it dont respond.

please help, a million thanks!

I try to restart network or suspend the process nothing works. If I could make firefox reopen to it's original state+ cookies; no site reloaded and get back my incogico it would be much appreaciated.

Hello=)

I am using Firefox v128.2 esr 64bit on big sur 11.7.10..

In firefox there is always this white line on top of the screen when fullscreening a yt video... (but also partial bars in other situations-randomly) (temp workaround : cmd+up arrow . But, whenever you pause or press something it reappears.

Can we please implement a more elegant solution?

Thanks a bunch , dear Mozillians=)

Have an excellent day=)

I've found a solution to the blurriness of the emojis, I've put it in the end of this post, in bold ⤵⤵⤵

My problem is that emojis look bad on Firefox compared to Edge_128.0.2739.79. Two screenshots are attached of bing.com & a Google Doc (left half of both pictures is Edge, other half Firefox). The problem persists on all the sites to a varying degree.

Steps to replicate: A] Open 2 sites in latest Edge & Firefox on Windows 11 (the examples that I've used in the screenshots): https://www.bing.com/ and an Empty Google Doc. B] In the search field of bing and in a new line in an empty Google Doc, copy the following example emojis (That were inserted using the 'Windows_Key+V' which summons the emoji Keyboard of Windows): 🏀🚕 C] Compare the quality of the emojis rendering between the browsers when unzoomed and when zooming.

I've tried in FF (to no avail): A] Disable hardware acceleration in settings (w/ FF restart). B] Setting "gfx.font_rendering.cleartype_params.rendering_mode" from -5 to 5 (w/ 10+ FF restarts). C] Setting "gfx.webrender.quality.force-subpixel-aa-where-possible" to true (w/ FF restart). D] Using both emoji sets in the "Segoe UI Emoji" & "Twemoji Mozilla" fonts in the "font.name-list.emoji" setting, both sets gave me blurry results (w/ FF restarts). D] Disabling all add-ons (w/ FF restart). E] Setting new Firefox separate clean install. F*] In Windows setting the scaling factor to 100% in Windows->System->Display->Scaling_Factor (w/ FF & Windows restart).

How can the blurriness of the emojis be fixed so to make them crystal sharp like in Edge?

Solution: A} Download Noto-Color-Emoji font from https://fonts.google.com/noto/specimen/Noto+Color+Emoji Ensure that your are getting the full resolution font (which came at ~23MB as of 2024.09.23) B} Unpack the font and install according to the on screen instructions. C} In FF in "about:config" find the "font.name-list.emoji" setting and rewrite its value field to "Noto Color Emoji, Segoe UI Emoji, Twemoji Mozilla" (w/o the quotations marks). D} I've attached a screenshot w/ the result, It is marked w/ the red writing of font.name-list.emoji on it.

Hi,\

Over the past week or so, my homepage refreshes intermittently and all of the time when I close tab. When I am on my homepage to read (MSN), I typically use the right click command to open the links in a new tab so I can keep the article in the homepage there. Every time I close the news tabs, the homepage refreshes. If I am just sitting on the homepage for few minutes, it auto-refreshes.

This does not happen on Edge or Chromium and I have been back to Firefox because I want more control over not having AI functions and Chromium still has serious limitations. But this is annoying. I have tried changing as many of the relevant settings in about:config that I could find to no avail. My PC an All-in-One 6 core Ryzen 7 with 16GB of RAM, which is far more than enough to handle the memory hog Firefox is (sometimes it eats nearly 2 gigs).

Any thoughts?

Thanks, Tom

Hi there,

Firefox is my default browser but increasingly (once a week I guess) I have to use chrome to access some sites. This happens with firefox only, (not other browsers) on some sites. The latest site is https://www.skyscanner.ie/. (see screenshot below).

Any ideas?

Thanks Andrew

My environment is windows 11 on a lenovo yoga slim7X using the ARM64 chipset

The screenshot function seems to have a bug. The function works as far as selecting "save full page" or save visible" but the image download never happens. Version is up to date and I have restarted but the issue persists.
