Diễn đàn hỗ trợ Firefox

I updated my desktop browser today and now there is an expandable sidebar at the left margin of the window showing tool icons for Tabs from other devices, History and Customize sidebar. I can see how to remove tool icons and how to expand or collapse sidebar but can I remove the sidebar completely? Is this an option? I prefer the old look with the browser web page content extending all the way to the left of the screen, without the narrow vertical sidebar.

I just updated to the latest version of Firefox, and all of a sudden I have a new icon, Extensions, that looks like a puzzle piece, I cant seem to be able to remove it....at all.

The other day I accidentally pressed a keystroke that changed a Firefox setting, and now it thinks I'm on a mobile device/displays sites in mobile view where possible by default. This has persisted despite restarts of the browser and the computer and has been happening since Sunday (Australian time). I've tried opening the Responsive Design dev tool and I've sent screenshots to a techsavvy friend (I'm totally blind and use a screen-reader, so couldn't tell this was happening until I tried to use a site that had a radically different layout in mobile view), and aside from not seeing an exit button or a switch to change device mode, he couldn't tell what was going on.

I'm stuck and need help! I would like to unmobile my Firefox!

I prefer the tabs be below the bookmark bar, and successfully modified the CSS file to do this some time back. Now update 133 has once again pushed them up below the menu bar. What do I have to do to get them back where I want them this time? And why can't you just leave the tab location preference alone when doing updates?

Hello. In the past two days I lose my tabs when I shut down Firefox. I used to be fine using the X at the top right and when I restarted the browser, all my tabs would still be there. Then they started going missing, so I started using the menu option to exit the browser. The tabs still went missing.

Then I noticed the square icon button on the extreme left and have discovered that Firefox has different windows, and that one of them (see attached image) has all my tabs in it, while the current window does not.

I cannot change Window 2 to be the current window. There is no obvious function on the page, nothing in settings and google is useless - I just get pages of discussion of how to tab between different apps on the desktop.

How do I make Window 2 the current window? See image.

Thank you

I updated to version 133 today and was confronted with the vertical tab bar. I did not ask for this or want it, and now I can't get rid of the side bar, in fact I seem to have just made it worse / wider. How can I get rid of this (and block it) It is just taling up space on my screen. Please help.

I haven't upgraded browser versions for a while and I'm now going from 109 to 132. Pretty bad I know.

I'm having a number of issues but for this post I'd like to concentrate on userChrome.css.

In version 109, I had a custom font for the top menu bar, the top menus, the bookmark toolbar, the bookmark toolbar menus, and the right click menus. I did this by including the following in userChrome.css (as per [https://support.mozilla.org/si/questi.../1335097|here]:

1. navigator-toolbox { font-family:"MyFont" !important }

This worked great, but it is no longer working in version 132. Obviously I don't know in which Firefox version this stopped working.

Has this been disabled by Mozilla or has it been changed? If it's been changed, how can I achieve it now?

I'm very grateful for any help!

I realize Facebook doesn't have a spell check feature,but is there a way my browser, Firefox, which I already have spell check enabled can somehow spell check Facebook when I chat? Can someone help? Thank you.

Hi. I cannot use stripe payments. I am using FF vLatest and have added it to the popup blocker exception list and every other exception list I can find. I have done this for http://stripe.com and for whatever website is trying to use stripe. No stripe payments ever work and I always get the same error attached. I have tried another browser and it works. How can I find out at least what is blocking the payments so I can disable it?

Is it possible to bookmark a particular section of a page, whereas the bookmark will take you to that location?

Textmarker was suggested in another thread, but apparently it is no longer working.

I wanted to use the new VPN feature and the icon initially showed up in the top right, but it has disappeared and is not present in "customise toolbar" or privacy settings either.

Please how do I stop these floating windows above the tabs in Firefox 131.0? They mostly cover up the tabs and make it difficult to impossible to open or close tabs. The floating window only half shows up above he tab. This is just insane and makes using Firefox almost to much to deal with. Every time I get near a tab the floating window appears and tells me what the tab already tells me. Come on this is GARBAGE!

H E L P !!!! PLEASE....

Hello, how can I remove or hide "List all tabs" btn?

Set "browser.tabs.tabmanager.enabled" as "false" stopped working for me after update to version 131.0. Hiding the btn before version 131.0 was not a problem.

I saw in release notes that "List all tabs" got some changes. link

This issue is happening with every newly installed add-on, but not with add-ons installed on or before Aug 3, 2024. The add-ons are installed via addons.mozilla.org. To rule out the possibility that it's happening only with specific add-ons, I also installed one of the random recommendations on that page, Augmented Steam which has 54,248 users, and it happens with that one as well.

I'll click Enable, but the prompt appears every time I restart Firefox.

What I've tried (with a restart after each attempt):

• Clear the startup cache
• Delete extensions.json
• Delete compatibility.ini
• Via about:config deleted extensions.databaseSchema and extensions.getAddons.databaseSchema
• Excluded Add-ons from syncing

I've noticed the following in extensions.json for each of the recent add-ons after restart:

• syncGUID changes to presumably random new value
• active changes from true to false
• userDisabled changes from false to true
• seen changes from true to false

I am a bit confused about how to keep updating FF on my Windows 7 PC, given that after March my current version (115.17.0esr) may not work as intended. Until now I've always updated manually by downloading a small 343KB installer file that updated FF without changing any of my settings, logins and bookmarks. Hoping to simplify updating, today I set updates to "Automatically install updates (recommended)" with sub-option "When Firefox is not running". But just now a FF notification informed me it was unable to update automatically and provided a link to https://www.mozilla.org/en-GB/firefox/enterprise/?reason=manual-update. From the dropdown there I chose "Windows 64-bit" > "Firefox Extended Support Release (ESR)". The download is a 64MB file.

Since this seems to be a new installation and not a simple update, can I be sure it won't overwrite my current version and leave me without settings, logins and bookmarks?

I have loved FF desktop browser since I started using it per my boss in 2003. But I am so tired of the fact that EVERY SINGLE TIME you put out an update it breaks my access to the bank. EVERY SINGLE TIME. I waste HOURS reading articles, calling the bank IT dept, chatting with people who are on 3 calls at once, only to hear them tell me to "just use chrome." I clear the cookies, clear the cache, reboot, follow all the prompts in the settings and THEN the damned bank server doesn't recognize the device so it forces yet ANOTHER password change. It happened again TODAY and it makes me so sad but I cannot do it anymore. I am STILL now (going on 4 hours) trying to access the billpay page @ Xantanderbank. (ahem, secure codename) I am forced now, by this craziness, to use the imbecilic duckduckgo which is A) and offensive name and b) you KNOW it nowhere near the product you have built but I CANNOT DO THIS ANYMORE. Thank you for the time it takes to read this diatribe. I appreciate it.

New day, new glitch. Since the inception of weather showing on the Firefox landing page, it has accurately shown my location. Today, it is not only not my city, it is in another state. It also does not respond to my making a correction with my zip code. Can we expect a correction any time soon?

Is Firefox now a complete tool of Google ? about:preferences#search there is no way to delete google as search engine I have startpage and duckduckgo as alternative options listed and I can remove them, but google cannot be removed as the REMOVE button is not highlighted in case of Google. Why do you hardcode Google as the default browser for the URL bar ?

From the attached image you can see that the "Remove Tab" is inactive specifically for google. I tried absolutely all advice on the net, and nothing works. Firefox now seemingly FORCES us to use google. This behavior was not present in the previous firefox version I used. It immediately happened after update to 128.0.3 (64-bit).

Is google now hardcoded into firefox ? If so it is time for a hard fork in the firefox code. Hopefully it is not needed.

In addition Google was ruled to be a Monopoly today by a federal judge,

https://apnews.com/article/google-antitrust-search-engine-verdict-apple-319a61f20fb11510097845a30abaefd8

So it would be better for Mozilla/Firefox to not continue the monopoly and become an enabling party in monopoly lawsuits.

Is there anyway to configure network.http.rcwn.enabled to false via the policy located in the ''C:\Program Files\Mozilla Firefox\distribution'' folder?
