Navigation bar icon for about:blank

[Veit Kannegieser]

Hello,
usually i put a item with name [] and address about:blank in the navigation bar.
works fine, however the icon shown left of [] is that of an other url, and changes over time.
It would be nice to either have no icon, or the default globe used for unavailable icon.
regards.

Can you describe your situation a bit better, or provide screenshots?
Can you also describe your use case a bit?

I ask about your use case because it is possible you could simply make your new tabs open to about:blank and that might be what you want? Or have your home button navigate to about:blank and use that? (What are you using your home button for right now?) Or maybe some form of bookmark could be appropriate?

It looks like this:

The icon is actually for a differn location.
Dumping places.sqlite, i see

Code: Select all

CREATE TABLE moz_places (   id INTEGER PRIMARY KEY, url LONGVARCHAR,
  title LONGVARCHAR, rev_host LONGVARCHAR, visit_count INTEGER DEFAULT 0, hidden INTEGER DEFAULT 0 NOT NULL, typed INTEGER DEFAULT 0 NOT NULL,
  favicon_id INTEGER, frecency INTEGER DEFAULT -1 NOT NULL, last_visit_date INTEGER , guid TEXT, foreign_count INTEGER DEFAULT 0 NOT NULL, url_hash INTEGER DEFAULT 0 NOT NULL);
..
INSERT INTO moz_places VALUES(17,'about:blank',
  NULL,NULL,0,0,0,
  190,47,NULL,'3TgvB-krkCH0',1,175532304468422);
..
INSERT INTO moz_places VALUES(600,'https://reiseauskunft.bahn.de/bin/query.exe/dn?protocol=https:',
  NULL,'ed.nhab.tfnuksuaesier.',0,0,0,
  190,47,NULL,'96xCr9r484Rn',3,47358666046751);

so both have favicon_id 190,

which is cached as

Code: Select all

INSERT INTO moz_favicons VALUES(190,'https://www.img-bahn.de/s3/prod/v/img_responsive/favicon.ico', (icon data here...));

I see this problem on different machines, on longer existing profiles.
But can currently not recreate the issue from a fresh profile, where a NULL favicon_id is assigned correctly for about:blank.

Now i wonder about the usage/obfuscation of rev_host.

Also thinking about the usability again, maybe i should have used the home button for exactly that.

I corrected that by

Code: Select all

UPDATE moz_places SET favicon_id=NULL WHERE url='about:blank';

but today it is back with values

Code: Select all

INSERT INTO moz_places VALUES(17,'about:blank',NULL,NULL,0,0,0,1200,37,NULL,'3TgvB-krkCH0',1,175532304468422);

Decoding the time stamps:
https://packaging.gitlab.io/signal-cli/ ... e_Icon.png:
1688811541691669/1000 -> Sat Jul 08 2023 11:19:01 GMT+0100
could be time of opening the page plus a week.

https://packaging.gitlab.io/signal-cli/installation/:
1688207728985000/1000 -> Sat Jul 01 2023 11:35:28 GMT+0100
1688207729229000/1000 -> Sat Jul 01 2023 11:35:29 GMT+0100
would be the time stamp when storing as book-mark.

I will try to investigate what happens adding a line into moz_favicons with a very far away expiration. Or maybe a file:// refresh source.
