v1.26.0

### Changes

- New options UI to edit the characters replaced in file names, with a live preview and a button restoring the default tables
- New `animateInfobar` option, on by default, turning off the blink and the expanding ring of the infobar (#1504)
- The `insertCanonicalLink` option now has a checkbox on the options page
- The auto-settings table column labels are noun phrases, carry a description for translators, and show their full text in a tooltip when the column clips them
- `single-file-core` updated from 1.6.1 to 1.6.5

### Fixes

- The status icons of the log panel are readable in dark mode
- The "display the infobar" label of the editor options was empty: the message key was spelled `optiondisplayInfobarInEditor`
- A resource answered with 401, 403 or 404 is retried with a referrer only when there is one to add, instead of being requested twice
- Mistranslations and typos fixed across the locale files, the four missing help entries translated to Chinese, and the literal values of the Chinese help page repaired
- The maximum appended data length follows the core constant instead of a local copy
- A font declared `oblique` with a slant angle range is no longer removed as unused (core)
- A file name trimmed to the maximum length keeps its whole extension (core)
- A replacement left empty in the file-name tables falls back to the default replacement character (core)
