הדפדפן הישן שלי לא פותח את העמוד הזה, אבל בדפדפן אחר הכול עובד.

That is the normal Hebrew order.

• The noun comes first: דפדפן = browser
• The adjective comes after it: ישן = old
• A possessive word like שלי = my often comes at the end of the whole noun phrase

So:

• הדפדפן הישן שלי = my old browser

This is different from English, where you usually put everything before the noun: my old browser.

A similar pattern:

• הספר החדש שלי = my new book
• החבר הטוב שלי = my good friend

Because in Hebrew, adjectives agree with the noun in definiteness.

If the noun is definite, the adjective must also be definite.

So:

• דפדפן ישן = an old browser
• הדפדפן הישן = the old browser

You cannot normally say הדפדפן ישן if you mean the old browser. That would sound like the browser is old in a sentence, not a single noun phrase.

So in הדפדפן הישן שלי, both the noun and adjective are marked as definite.

Because the subject is הדפדפן = the browser, and דפדפן is grammatically masculine singular.

In the present tense, Hebrew verbs agree with the subject in gender and number:

• masculine singular: פותח
• feminine singular: פותחת
• masculine plural: פותחים
• feminine plural: פותחות

So:

• הדפדפן ... פותח = the browser opens
• התוכנה ... פותחת = the program opens, if the noun is feminine

Hebrew does not use a helper verb like English do / does in the present tense.

To negate a present-tense verb, you usually just put לא before it:

• פותח = opens / is opening
• לא פותח = does not open / is not opening

So:

• הדפדפן הישן שלי לא פותח את העמוד הזה = my old browser doesn’t open this page

This is very normal Hebrew structure.

את is the direct object marker. It appears before a definite direct object.

Here, העמוד הזה = this page is definite, so Hebrew uses את before it:

• פותח את העמוד הזה = opens this page

את does not have a separate meaning here like with or to. It just marks that the page is the direct object of the verb.

Compare:

• אני קורא ספר = I am reading a book
• אני קורא את הספר = I am reading the book

So את usually appears when the object is definite: the..., this..., that..., a name, etc.

In Hebrew, demonstratives like this usually come after the noun.

So:

• העמוד הזה = this page
• הספר הזה = this book
• הילדה הזאת = this girl

This is the normal pattern: noun + this/that.

Also, the noun is usually definite:

• עמוד הזה is not standard
• העמוד הזה is correct

So Hebrew says literally something like the page this.

Because ב־ is a preposition prefix in Hebrew. It attaches directly to the word that follows.

Here:

• ב = in / with / on
• דפדפן = browser
• בדפדפן = in a browser / with a browser / on a browser

This attached-preposition pattern is extremely common:

• בבית = in the house/home
• בספר = in the book
• במחשב = on the computer / in the computer

In this sentence, בדפדפן אחר means something like in another browser or with another browser.

Because אחר here means another, not the other.

So the phrase is indefinite:

• בדפדפן אחר = in another browser

If you wanted in the other browser, you would normally make it definite:

• בדפדפן האחר

Also notice that אחר is an adjective, so like other adjectives in Hebrew, it comes after the noun:

• דפדפן אחר = another browser
• הדפדפן האחר = the other browser

Hebrew prepositions often cover a wider range than their closest English equivalents.

The prefix ב־ can mean:

• in
• on
• at
• sometimes something close to with or using, depending on context

So בדפדפן אחר is literally in another browser, but in natural English you might translate it as:

• in another browser
• with another browser
• using another browser

All of those capture the idea.

Because הכול = everything is treated as singular in Hebrew.

So the verb is singular too:

• הכול עובד = everything works

Hebrew uses masculine singular agreement here.

You will often see this with general words like everything:

• הכול בסדר = everything is fine
• הכול מוכן = everything is ready
• הכול עובד = everything works

Also, you may see the spelling הכל as well. Both refer to everything; הכול is a common fully spelled form.

Yes. עמוד literally means page, and in many contexts it can also mean a web page.

Depending on context, Hebrew speakers might also use other terms, such as:

• דף = page/sheet
• עמוד אינטרנט = web page
• דף אינטרנט = web page

But in a sentence about a browser opening a page, עמוד is perfectly understandable and natural.

So here העמוד הזה clearly means this page, most likely this webpage.
