Forum pomocy dla programu Firefox

As of a week or two ago I can no longer save URLs to bookmarks folders in my bookmarks toolbar. I can drag and drop it but nothing happens, does not save in that folder. Neither can I save a URL via clicking on the star then choosing a folder. Doesn't stick in the folder. How can I fix this.

Hi When I'm watching videos on Firefox especially while on YouTube, the whole browser turns white for a few seconds. It sometimes pauses the whole video but almost every time the audio is still playing and I can't see the video. I looked at other similar problems but turning on and off hardware acceleration does nothing. I have the latest GPU drivers and I'm using a laptop.

I'm having an issue where PDF files I download are blurry when I zoom in on them in Firefox, but when I use, for example, Edge, it zooms in fine. I've tried reinstalling Firefox, but it didn't make any difference. It happens to all PDFs I've tried.

When using an email "button" on a website to contact the owner, the email composition box that pops up always fills in the From line with my iCloud email address. How do I change that (permanently) to a different account?

My Firefox account is synchronized across my personal devices and my work laptop. This has been working fine for a while, until today I got an error on my work laptop that "Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile". I suppose this is because it's using version 102.12.0esr, whereas my PC uses version 114.0.

My workplace won't let me just install the normal version of Firefox.

So in my search for a solution, my first hope is that someone can provide some magic solution, maybe?

If there is no such thing, I'd like to know if there's an esr version right around the corner that will fix this?

In the event that I'm all outta luck, what I'd like to be able to do is try to disconnect my profile on the laptop from synchronization, and then force it to open, hopefully it will work and then I won't have synchronization anymore but at least I'll have my profile as it currently is. Can someone tell me how to do this, if it's possible?

What I absolutely want to avoid at all costs is to manually rebuild my profile. Restoring all my settings, including those hidden in about:config, and all my extensions' settings by hand is going to be a nightmare.

Any help is appreciated. Thanks.

I'm on the latest non-beta version of Firefox on my PC, but my problem has been happening for over a month now. Whenever I add a new bookmark, Firefox has started remembering the last folder I saved a bookmark into. That's not really a helpful feature but, worse still, it doesn't actually save the bookmark into that folder but saves it into Bookmarks Menu instead. I then have to add the bookmark again and choose the folder I want to save it into, as on the second attempt it defaults to Bookmarks Menu as the location. Sometimes the new bookmark remains in the Bookmarks Menu after the second save regardless of what other folder I select. I haven't checked to see if the bookmarks are being duplicated in that scenario.

I've been assuming that this was a bug and have been expecting it to be fixed, but there have been several new releases of Firefox since I started having the problem and it still remains. Moreover, I can't find anything online to suggest that other people are having the same issue, which makes me think it's something to do with my system.

I'd be grateful for any assistance you can provide please.

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.

In the last few days, I have noticed that a number of websites are throwing me SSL_ERROR_NO_CYPHER_OVERLAP errors. Most websites, particularly more modern websites, seem to not have this issue. As some more professional examples, www.twitch.tv and www.dndbeyond.com throw this error. I have tried setting temporarily TLS version fallback limit and min to 0, with no change. I'm not really sure how to go about debugging what cyphers these websites do support and why they are throwing these errors. Any help on where to start would be greatly apprecaited.

Firefox 114 introduced hidden support for nvidia video super resolution. In about:config you can enable preference gfx.webrender.super-resolution.nvidia to make it work. However I see 0 difference on all videos on all pages. I have everything in nvidia control panel set correctly (VSR enabled and set to 4/4 quality).

Tried to find more info online and someone on reddit complained that it worked before but it stopped working with latest firefox beta (probably before final 114 release): https://www.reddit.com/r/firefox/comments/13duluz/nvidia_video_super_resolution_comes_to_firefox/

I tried using logic too - if this pref is related to webrenderer in its name maybe it is not working because I am not using webrenderer? However I checked about:support and in section graphics->composition I have "webrenderer" so it seems I am using it, but its VSR feature is not working at all.

I set my browser to use English instead of my local language and I expect sites to use English by default. Now for some reason Gmail showed me a "do you want to leave this page" browser dialogue in language other than English.

Turns out, there's a new(?) option to set alternative interface languages, and I suppose websites can now choose which one to use?

Wow, just noticed, even tooltips on this website aren't in English anymore. This is extremely annoying.

I'd love to remove the alternate language from that list and leave Firefox interface exclusively in English. There is no option to remove the second language, only to move priority (see screenshot).

Searching through about:config with "language" didn't help. The closest relevant result was for the dictionaries. I do not have problems with dictionaries; "alternate" did not bring any relevant results either.

Hi,

I'm trying to configure equipment on my local network. Some of the equipment does NOT support https. Firefox continuously changes the address http://192.168.xxx.xxx to https://192.168.xxx.xxx, and the connection fails!

I have tried the various options in HTTP Only Mode, including entering Exceptions. I have also temporarily changed network.trr.mode from 5 to 1 (and 0), but nothing is working!

What can I do?

Thanking you Pedro

Hello, I'd like some help with a performance issue. Basically, when using the theme "Pixel-Punk" while playing a video, ram usage by the GPU slowly increases. It increases until it reaches 8GB, where Firefox will soft crash, displaying a white screen. Firefox will be reloaded, with the animated banner portion in Firefox usually disabled or flickering on and off. The GPU item in the process manager also disappears and ram usage no longer increases. The slow nature of the problem makes it hard to diagnose but I'm fairly certain it's due to this theme. The problem doesn't appear with it off, or even on, until I start watching a YouTube video, where ram usage will slowly increase. If I disable the theme ram usage stops increasing but doesn't decrease to it's previous state. I've also tried refreshing Firefox but that didn't help. Also, I don't have an option for hardware acceleration so I can't troubleshoot that option. I've asked the Firefox subreddit and I was guided to the profiler, but that's a little over my head. Is there a way to fix this? I quite like this theme, and I haven't seen any complaints in the reviews. There are also lots of variables, like the extensions I have, my hardware configuration and such. my hardware for info: laptop - Lenovo Legion 5i Pro Gen 7 (2022) CPU- 12700H RAM- 16GB GPU- 3070ti

Good afternoon,

I've got a problem with add-ons while using Squid MITM Proxy with a custom certificate for Firefox/LibreWolf.

While I'm trying to update / install an extension / theme, it fails with:

``` 1686147276233 addons.xpi WARN Download of https://addons.mozilla.org/firefox/downloads/file/4104397/witchdoctor-2.0.xpi failed: [Exception... "Certificate issuer is not built-in." nsresult: "0x80004004 (NS_ERROR_ABORT)" location: "JS frame :: resource://gre/modules/CertUtils.sys.mjs :: checkCert :: line 177" data: no] Stack trace: checkCert()@resource://gre/modules/CertUtils.sys.mjs:177 onStopRequest()@resource://gre/modules/addons/XPIInstall.jsm:2514 ```

How can I install an add-on while using the MITM proxy?

The remote Windows host contains a web browser that is affected by multiple vulnerabilities. Description

The installed version of Firefox is affected by various security issues, some of which could lead to execution of arbitrary code on the affected host subject to the user's privileges.

Solution Upgrade to Mozilla 1.7.1 / Firefox 0.9.2 or later Upgrade to Mozilla 1.7.3 or later. Upgrade to Firefox 1.5.0.9 / 2.0.0.1 or later. Upgrade to Firefox 1.5.0.11 / 2.0.0.3 or later Upgrade to Firefox 1.5.0.10 / 2.0.0.2 or later Upgrade to Firefox 1.5.0.12 / 2.0.0.4 or later

Where are the patches/updates for this vulnerability located on the Mozilla homepage?

I know there are ways , with more clicks or longer shortcuts to get to some folders but this is the main and most easily accessible way to get to my bookmarks. I know this has been discussed in some older posts but they are all archived so I can't ask any questions there. Sorting by name, for me, is quite inconvenient as sometimes the bookmarks title isn't immediately, easily remembered. Thanks.
