The new Firefox 133 sidebar won't disappear

Hello,
My DELL "tower" PC, purchased refurbished in 2021, updated to the new version of FIREFOX 133 automatically on 11/26/24.
However, since then I have the "Sidebar," which I have no use for, that is permanently displaying on the left side of the screen!
I've tried everything: it's impossible to get rid of this sidebar that takes up at least 10 cm of my view on the FIREFOX browsing screen.
Can someone help me make this "Sidebar" go away please?
Thank you in advance
Hervé F.

Hello,
Removing the left vertical sidebar with the Firefox configuration editor:
Open Firefox or open a new tab.
Type or copy-paste ==► about:config
Press the '' Enter'' key on the keyboard.
Or click on ''about:config'' then paste and open.

Click on ==►Accept the risk and continue.

In the ''Search preference name'' box:
Copy-paste ==► sidebar.revamp
If the preference is bold and has a value of true, double-click it to restore the default value of false.

Close Firefox.
Restart Firefox.
Experimental feature:
It may be an experimental feature: Firefox Labs
Open Firefox or open a new tab.
Type or copy-paste ==►about:preferences#experimental
Click on ==► Default configuration

Close Firefox.
Restart Firefox.
Increase or decrease the Firefox sidebar:
When the sidebar is open "Ctrl + H" position the pad or mouse cursor to increase or decrease it.
Hold the cursor on the double arrow, move to the right (increase) or to the left (decrease).
Release the cursor when you find the right distance:
Hello,
Which sidebar?
- History (Ctrl + H)
- Synced tabs (down arrow, Close sidebar)
- Bookmarks (Ctrl + B)
Or something else?
Hello,
Thanks to you, I was able to resolve, (by following your instructions), one part of the problem.
Instead of having a side panel almost 12 cm wide on the left of my screen, under FIREFOX V. 133; at least 8 centimeters have disappeared when I pressed "Ctrl + H" then "Synced Tabs", "Close Side Panel".
But, apparently, with this new version of Firefox 133, a "Side Panel" of 3 or 4 cm remains permanently on the left side of the screen. (or on the right, I can only switch it but can't make it disappear)...
Maybe we'll know more in a few days, as this version has just been updated.
Even though my problem is not completely resolved, thank you very much.
Best regards

Good evening,
Thank you very much Mr. "Pistouri"!,
I have completed step no. 1: Remove the left vertical sidebar using the Firefox configuration editor:
And it worked! I no longer have a sidebar on Firefox v 133; neither on the left nor on the right!
Thank you very much and looking forward to it!
Best regards
