Firefox Community Forum

A sidebar has appeared out of nowhere. I removed all extension on that sidebar and it still doesn't go away. I already have a bookmark bar and extensions at the top bar. I don't want another sidebar at every firefox window. How do I remove the sidebar, please.

I was excited to see that Firefox had support for Canadian English, however the dictionary seems to be missing numerous words and I get spelling errors for words like "lasagna."

Is this a bug or is the dictionary just barely populated with words and missing a tremendous amount?

I often receive a 403 error when using Firefox Every time, before this happens, I get the unsafe website warning and then the 403 error when I continue anyway

I am using the latest version at the time of writing These errors only occur on my desktop PC I have tried to replicate this issue on both my phone (Android) and another laptop(Windows 11) but all the websites work normally on there.

I have tried the following, none of which have any effect:

• Clearing cookies
• using Troubleshoot mode
• Restarting
• Changing Useragent
• Using "Forget about this site"

The following do fix the issue

• Using a VPN
• Using Google Chrome
• Running Firefox in another profile

Going through the privacy and security tab and reseting all the settings sometimes works but only temporarily

The following are a few websites where the issue occurs

1. https://kdice.com/
2. https://latinitium.com/
3. https://theysaidso.com/
4. https://opensource.org/
5. httpe://obsidian.rocks/

Well looks like they did it to us again. My tabs are back on top again and need to put them below where I am a lot of other users like our tabs!

Below is my current coding if anyone knows how to adjust it to force the tabs to the bottom again would be much appreciated!!

Current version I am running of FF is 133.0

When the latest version is released, if I continue browsing without pressing the update button, the process suddenly becomes slow or freezes until I restart the device. Why is this? There are no problems until the update arrives, but as soon as the update arrives, the device becomes unstable, and after the update, it works as if nothing happened.

　I am using Google Translate, so the nuances may be different.

I've noticed since a few upgraded of Firefox tat I am having an issue loading my local uTorrent GUI at: https://192.168.0.xxx:36724/gui/index.html. I am currently using 132.0.2 x64 and it eventually loads after 3-4 minutes. There are absolutely zero add-ons at the moment, and it does not matter if it is a portable version or standard installed version. I do not seem to have this issue while using Firefox (latest) ESR portable version.

Is there something I'm missing here? I am not sure if it is the port that's the issue with Firefox, because I have a local website using port 9090 and 8080 without any issues on loading. Also, it is happening with the nightly version of FF as well. All other browsers load quickly.

Kind regards,

Hi,

I have a sidebar that appears to be permanent and I cannot make it go away.

I opened firefox, went to reopen the previous session tab with control + shift + t, and my fingers slipped and hit the wrong combo of buttons.

Then this thing appeared. This sidebar. I looked for similar questions on the topic, but it is not the history or bookmarks sidebar that pops up from control + h or control + b. I love hotkeys.

So my question is, how do I disable the dang thing?? I tried going into custom tools, I tried looking into settings, but I really cannot find this. And it seems that other issues are usually to due with bookmarks/history sidebars - which I don't believe to be the issue here..

Any help is greatly appreciated!

It's the sidebar on the left in my image if that provides any further info!

Thanks :)

Another update, another repeat of the same question: How do I return tabs on bottom in Firefox V133?

I switch between tabs a lot so it is far more efficient for me to have them closest to the browsing window

Thanks

I need help making disappear the lateral bar but looks imposible, I have tried deleting this from customize toolbar but I still see it, I do not want it because it takes space from my really small laptop screen.

This problem started when I updated the laptop and I guess firefox also

I have the setting browser.search.openinnewtab and also browser.urlbar.openintab both set to true, but when I type a search into either the address bar or the search bar next to it, instead of opening a new tab, it puts that search into an already-open blank tab, if one is already open.

I often use blank tabs to separate my currently open tabs into groups by topic and whatnot, so it's incredibly annoying when the search bar takes over one of my adhoc 'separators' instead of opening a new tab like I want it to.

Is there a setting to force the search bar to always open a brand new tab, even if 'new tabs' are already open??

My search bar is taking up the entire screen when I try to interact with it. When I go to search stuff, then it returns to the normal style. Then, when I try to interact with the page I'm on, it absorbs the screen.

I never feel like webpages scale properly when I visit them. There is always content left off screen or I have to zoom out so much that the text is too small to read. Is there a setting I can change to affect this?

This webpage is particularly egregious: https://www.desktopmetal.com/products/shop

My Firefox Nightly version is: 135.0a1 (2024-11-26) (aarch64). My computer is a: MacBook Air (15-inch, M2, 2023) running macOS Sequoia (Version 15.1). I have been having these issues for a long time regardless of computer.

I have attached a picture of the labs settings I have enabled but I cannot see why any of them would affect this.

The latest update to Firefox includes a new Review Checker. It is activated by pressing the price tag in the address bar when on a specific product page in Amazon, etc. This price tag does not appear on my laptop when I am on a product page. Is there an activation method I am not using? How do I get the price tag to appear?

I've asked about this before but got no help Firefox is my browser of choice. Occasionally, I find in necessary to use Chrome.

The vast majority of time, when are both are active at the same time, one or both crash, like today. Firefox closed abruptly, then the crash report appeared. I have the crash report. Chrome froze up, and had to be shut down in Task Manager.

It only occurs in this scenario. Rarely does Firefox crash otherwise.

Can someone please advise where to go to get help?
