Bug: Recent problems copying urls from location bar
Status: RESOLVED
Priority: P3
Resolution: INCOMPLETE
Created: 2023-02-08 21:22:26+00:00
Resolved: 2023-05-18 13:26:44+00:00

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/109.0

Steps to reproduce:

Something has recently changed which is sometimes preventing urls from being copied from the location bar (where the url for the page is displayed/entered).  It is an intermittent issue.  Every time I have noticed the copy problem, I am on a non-secure (http vs https) url.  For that case, I am usually able to work-around by using right-click and copy instead of the highly preferred Ctrl-C.  It usually takes me a minute or two to realize why the copy did not work.

A second recent issue is that the url fragment (the part after the #) did not get copied when using Ctrl-C.

I am running Ubuntu 22.04 with the latest Firefox snap (109.0.1).


Actual results:

Actual:  Ctrl-C does not always work on location bar


Expected results:

Expectation:  Ctrl-C always works on location bar

2) I went to Settings -> Searched for popup -> Enabled blocked popup window -> Then went to exceptions.
3) Created an entry for google.com


Actual results:

3) Navigate to about:debugging -> This Firefox -> Temporary Extensions
4) Select 'Load Extension' and install the unzipped extension from step 4
5) Type `@google omni 123` in the address bar

Actual results:
The extension's keyword is activated and the extension receives events

Expected results:

This isn't intended behavior, right? It feels very broken.

Bug: OpenSearch telemetry for secure/insecure engines may use the search form rather than the search url
Status: RESOLVED
Priority: P2
Resolution: FIXED
Created: 2023-02-09 11:21:52+00:00
Resolved: 2023-02-10 05:13:11+00:00

When we added the telemetry for insecure/secure OpenSearch engines in bug 1789438, we got the search url from the engine using this:

`engine.getSubmission("").uri;`

However, if the string passed to `getSubmission` is empty, then it might return the searchForm: https://searchfox.org/mozilla-central/rev/28c0d45a553fd2817ac14e1562435e86dc0aa403/toolkit/components/search/SearchEngine.sys.mjs#1425,1427-1429

If the search form doesn't exist, then it will fallback to using the standard search URL:

https://searchfox.org/mozilla-central/rev/28c0d45a553fd2817ac14e1562435e86dc0aa403/toolkit/components/search/SearchEngine.sys.mjs#1381,1391

I think in most cases, OpenSearch entries are unlikely to have search forms - especially as this is a non-standard property that Mozilla used previously.

However, I'd still like to update the code, so that this gets properly reported, and we can check for any changes in the numbers.
Bug: Dragging the search bar in customize mode to the tabs bar makes it unusable

**Expected result**
- The search bar adjusts its width according the number of the tabs opened

**Actual result**

Bug 1790616 - Use modern flexbox for the toolbox. The min-width / contain are as usual to allow elements to shrink under
their intrinsic size. You can only see its effects with relatively thin
windows (or with a very large number of tabs in the tabstrip case).

Bug: Text overlap in Preferences > General > Applications with long content type

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:109.0) Gecko/20100101 Firefox/111.0

Steps to reproduce:

Open Firefox > Preferences > General, and scroll to the 'Applications' section. If a value has a long content type, it overlaps the 'actions' column. I don't know the source of this content type value.


Actual results:

Text is overlapping, preventing the actions column from being readable. In addition, selecting the row with the overlapping text causes the entire table to resize.


Expected results:

The content type column should truncate text if it is too long.

**Affected versions**

**Tested platforms**

**Steps to reproduce**

2. Right click on the bookmarks toolbar and select Add Folder
3. Click on X on the browser window
4. Open Firefox again from the dock 
5. Try deleting any item in the bookmarks toolbar

**Expected result**
- Bookmarks toolbar doesn't lock up

**Actual result**
- The folder is created, the bookmarks toolbar is locked up, and the only thing that works is to create new folders (delete, copy, cut, paste doesn't work at all)

**Regression range**
- Mozregression pinpointed between 2021-04-14 and 2021-04-15 with this following [pushlog](https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=e105fb5fb5cfef90d80a69e121f971a08df83e64&tochange=48a99646f183abc34e8eeb695fcede5bcc9463d1) as it wouldn't bisect any further unfortunately.

**Additional notes**
- The issue can be seen in the following [attachment](https://drive.google.com/file/d/1Pt3WeGSQdfnlt0R4YC3m1QGRrYPM0VHP/view?usp=share_link)
- On the unaffected builds, the X button on the Firefox window is disabled when creating a new folder.
- The only workaround is to fully close Firefox and launch it again.
