Сегодня 23.04.2026, я открываю браузер и вижу, что моя строка и ярлыки находятся сверху, а не в центре(1 скриншот). Вчера 22.04.2026 все было хорошо, я покажу на 2 скрине как это должно выглядеть. Хочу заметить что у меня включена функция Handoff и она мне удобна, но мне неприятно видеть блок с ярлыками и строкой не по центру. Я использую тему ffultima, скажу еще раз, вчера все было нормально. Версия фаерфаокса у меня - firefox developer edition

When we are getting dates and time in history like Chrome? Random months and in those months, no days, no dates makes Firefox outdated.

Is Firefox not growing or everything needs to be highlighted? I have never highlighted anything to chrome yet it has done things that are worth it.

Up to 126.0b9, files with encoded URLs in their filenames downloaded normally. As of 127 onward, however, it gets changed to _3A instead of %3A, etc. Is there a setting somewhere in config to revert this?

Example:

Supposed to be: test [sound=https%3A%2F%2Ffiles.catbox.moe%2Fe547nk.mp3].png Downloads as: test [sound=https_3A_2F_2Ffiles.catbox.moe_2Fe547nk.mp3].png

On the about:sync page the button to "Export to File..." button has no effect. Regardless if I select "Limit history engine fetch to first 5000 records" or "Anonymize Data".

It used to work. So I wonder why nothing happens when I click the button now... There is no network call made when I click the button. No error.

Good morning, I'm running Firefox Developer Edition 143.0b6 on Linux Mint 22.1. A couple of weeks ago I noticed that when moving tabs on the left-hand side they'll instantly get locked into an inscrutable and seemingly impossible to fix "pinned mode". Is there a way to turn this off? It is driving me crazy. I've looked through Settings > General > Tabs and about:config and didn't see anything relevant. If anyone has run into this or knows a workaround, I’d be grateful to hear it.

There's one specific field I fill in very often and for some reason Firefox is really keen on suggesting me two searches that I looked up more than a couple months ago, on a totally different site. I can't even remove these suggestions or add new ones. When I used Vivaldi, it'd learn what I insert (even if it'd end up suggesting tens and tens of options), while Firefox doesn't learn at all.

For sake of an example, let's say that the word I use every day in this field is XYZ. Not even once was it suggested to me, I've only ever gotten the two in the screenshot below instead. And I can't remove them using the Delete key as some other article suggested.

Speaking of which, I just noticed the same thing happen to the subject line in this form 🙃

When signing in to websites, firefox offers e-mail address options that havebeen used before on that site. But right now it keeps offering two, one of which is incorrect, and I thought there was a way to fix that, but right now I cannot remember it.

This is explicitly for sites where I have told firefox *not* to save the password, and it is offering up potential email/login. entries *only*.

I do not want to tell firefox to not offer to autofill anything ever, because that saves time when the entries are correct. but here they are *not* correct and I need to clear them for this one specific website.

How do I do that?

Dear Mozilla Geeks—

As practically every other Firefox user, my bookmarks evolved into a lengthy file system that uses folders to segregate categories of bookmarks.

That is, it used to have this feature.

After the last update all or most of the bookmarks (I can't tell by scrolling down the long list) are devoid of their organizing folders. This puts a great deal of information beyond easy reach. In Mozilla Help topics one is advised to click on the library icon in the toolbar ... only there is no such icon on my copy of Developer's Edition.

Can someone suggest a method or methods to recover the folders?

Some passwords have been lost as well.

Yours Sincerely,

Glen

I've been seeing this more and more, but my toolbar will change by itself every restart. The add tab button will shift all the way to the left or not appear, the bookmarks won't appear, etc. I'm not sure what can be causing this, and I saw no way to "save" my current configuration other than pressing the done button upon using the custom toolbar, which I had done every time prior to fix my configuration. Does anybody know why this is occurring, and a possible fix? Thank you

When playing any Ren'Py web build on Firefox Windows, the frames freeze while entering inputs. Depending on what is being displayed on screen, sometimes it will still continue despite the mouse movement, but most things just completely freeze up. Once the inputs stop, the frames will skip ahead to where they should be. This only seems to happen on Windows, as I was told it is not repeatable on Ubuntu using Firefox. This is also not an issue on Chromium based browsers.

In English, the meaning of this error is: Title: Configuration error Content: Failed to read configuration file. Please contact your system administrator.

I had this error for a long time. But it's not too serious. Just hit ok and I can use all the recovery tabs as before without any problems. But every time I open windows and open the browser, this message appears. I feel very uncomfortable and tired without knowing why. Even reinstalling the browser didn't fix the problem, I tried it before and lost my favorite browser theme. And 1 more thing if someone can explain. If it can't read the configuration file, how can I still use the browser? What does that configuration file do?

This message only appears when I have not opened the Firefox browser on my computer. If I already have the tab, I can open another firefox browser without that message appearing. Only when I close all tabs. Open it again and it will appear. And click ok to use normally.

Hi,

On this site:

https://www.opensubtitles.org/en/search/sublanguageid-eng/idmovie-1380901

selecting a sub and trying to download gives "The page is not redirecting properly"

I am using Firefox Developer Edition 127 b07, and that happens also in safe mode.

It used to work not too long ago with FF, and it works with Chrome latest.
